Hydrothermal Assembly of a Novel Three-Dimensional Framework Formed by [GdMo12O42]9- Anions and Nine Coordinated GdIII Cations

Abstract: The three-dimensional framework of [Gd(H2O)3]3[GdMo12O42]vdt·3H2O, which was synthesized from hydrothermal reaction, is built up from Silverton-type anions linked by nine coordinated gadolinium(III...

Hybrid coordination polymer constructed from β-octamolybdates linked by quinoxaline and its oxidized product benzimidazole coordinated to binuclear copper(I) fragments

Abstract: The one-dimensional polymer, [Cu2(C8H6N2)2(C7H6N2)]2[Mo8O26] (1), which consists of β-[Mo8O26]4- anions linked by quinoxaline and its oxidized product benzimidazole ligands coordinated to binuclear copper(I) fragments, provides the first demonstration that the isolated copper(I) complex under hydrothermal conditions “captures” the reduction product of original starting organonitrogen ligand to form a copper(I)−β-octamolybdate complex.

Three Polymeric Frameworks Constructed from Discrete Molybdenum Oxide Anions and 4,4‘-bpy-Bridged Linear Polymeric Copper Cations

Abstract: Three compounds, [Cu(4,4‘-bpy)]2MoO4·2H2O (1), [Cu(4,4‘-bpy)]2Mo2O7 (2), and [Cu(4,4‘-bpy)(nic)(H2O)]2Mo8O26 (3), are synthesized by hydrothermal reaction, which suggests that oxomolybdate−organic ligand coordination transition-metal fragments can merge their merit to generate some interesting architectures. Crystal data for [Cu(4,4‘-bpy)]2MoO4·2H2O (1): monoclinic system, space group C2/c, a = 10.936(1), b = 17.775(1), and c = 14.484(1) A, β = 110.15(1)°, and Z = 4. Crystal data for [Cu(4,4‘-bpy)]2Mo2O7 (2): orthorhombic system, space group Pbcn, a = 11.841(1), b = 9.105(1), and c = 21.311(1) A, and Z = 4. Crystal data for [Cu(4,4‘-bpy)(nic)(H2O)]2Mo8O26 (3): monoclinic system, space group P2(1)/n, a = 11.457(1), b = 16.918(1), and c = 12.463(1) A, β = 92.6(1)°, and Z = 2. Compound 1 is built up from {MoO4} tetrahedra linking of 4,4‘-bpy coordination copper(I) chain fragments as a railroad-like framework. Compound 2 has noticeable structural features: two {Mo2O7} and four {CuO2N2} tetrahedra are conn...

Hydrothermal synthesis and structures of three new copper complexes: [{Cu(2,2′-bipy}2(β-Mo8O26)], [{Cu(py)3}2{Cu(py)2}2(α-Mo8O26)] and [Cu(py)2]4[(SO4)Mo12O36]

Abstract: Two interesting organic–inorganic hybrid solids [{Cu(2,2′-bipy)2}2(β-Mo8O26)] (1), [{Cu(py)3}2{Cu(py)2}2(α-Mo8O26)] (2), and a new two-electron-reduced Keggin-core compound [Cu(py)2]4[Mo12O36(SO4)] (3), were synthesized by hydrothermal methods and structurally characterized by X-ray diffraction. The structure of 1 consists of discrete [{Cu(2,2′-bipy)2}2(β-Mo8O26)] clusters, constructed from β-[Mo8O26]4− subunits covalently bonded to two [Cu(2,2′-bipy)2]2+ coordination cations via bridging oxo groups that connect two adjacent molybdenum sites. The structure of 2 consists of heterometallic dodecanuclear clusters, [{Cu(py)3}2{Cu(py)2}2(α-Mo8O26)], connected via π–π stacking contacts into an extended 1-D chain. Each [α-Mo8O26]4− anion forms weak covalent interactions to two [Cu(py)3]+ and two [Cu(py)2]+ units through terminal oxo groups of the octamolybdate cluster. A new compound [Cu(py)2]4[MoV2Mo10O36(SO4)] (3), with two-electron-reduced Keggin anions, was unexpectedly obtained from the similar hydrothermal treatment of 2. Compounds 1–3 are of interest due to their unusual Cu-coordination geometries; trigonal bipyramidal Cu(II), distorted tetrahedral, T-shaped trigonal, and linear Cu(I) are observed, and in 2, two distinct Cu(I)-coordination geometries are observed in the same structure!

Engineering coordination polymers towards applications

Abstract: The development in the field of coordination polymers or metal-organic coordination networks, MOCNs (metal-organic frameworks, MOFs) is assessed in terms of property investigations in the areas of catalysis, chirality, conductivity, luminescence, magnetism, spin-transition (spin-crossover), non-linear optics (NLO) and porosity or zeolitic behavior upon which potential applications could be based.

Polyoxometalate clusters, nanostructures and materials: From self assembly to designer materials and devices

Abstract: Polyoxometalates represent a diverse range of molecular clusters with an almost unmatched range of physical properties and the ability to form structures that can bridge several length scales. The new building block principles that have been discovered are beginning to allow the design of complex clusters with desired properties and structures and several structural types and novel physical properties are examined. In this critical review the synthetic and design approaches to the many polyoxometalate cluster types are presented encompassing all the sub-types of polyoxometalates including, isopolyoxometalates, heteropolyoxometalates, and reduced molybdenum blue systems. As well as the fundamental structure and bonding aspects, the final section is devoted to discussing these clusters in the context of contemporary and emerging interdisciplinary interests from areas as diverse as anti-viral agents, biological ion transport models, and materials science.

Hybrid Organic−Inorganic Polyoxometalate Compounds: From Structural Diversity to Applications

Abstract: Polyoxometalates (POMs) are discrete anionic metaloxygen clusters which can be regarded as soluble oxide fragments. They exhibit a great diversity of sizes, nuclearities, and shapes. They are built from the connection of {MOx} polyhedra, M being a d-block element in high oxidation state, usually VIV,V, MoVI, or WVI.1 While these species have been known for almost two centuries, they still attract much interest partly based on their large domains of applications. They play a great role in various areas ranging from catalysis,2 medicine,3 electrochemistry,4 photochromism,5 to magnetism.6 This palette of applications is intrinsically due to the combination of their added value properties (redox properties, large sizes, high negative charges, nucleophilicity...). Parallel to this domain, the organic-inorganic hybrids area has followed a similar expansion during the last 10 years.

Old materials with new tricks: multifunctional open-framework materials.

Abstract: The literature on open-framework materials has shown numerous examples of porous solids with additional structural, chemical, or physical properties. These materials show promise for applications ranging from sensing, catalysis and separation to multifunctional materials. This critical review provides an up-to-date survey to this new generation of multifunctional open-framework solids. For this, a detailed revision of the different examples so far reported will be presented, classified into five different sections: magnetic, chiral, conducting, optical, and labile open-frameworks for sensing applications.
