Synthesis and Structure of a Novel Molybdenum-Iron-Sulfur Cluster with Mo2Fe2 Core and All-Disulfide Chelate Ligands, (Mo2Fe2(μ3-S)4(S2CNEt2)5)CH3CN.

Abstract: The cluster compound [Mo 2 Fe 2 (μ 3 -S) 4 - (S 2 CNEt 2 ) 5 ]CH 3 CN has been prepared from the reaction system containing (NH 4 ) 2 MoS 4 , FeCl 3 , NaS 2 CNEt 2 , PhSH and NaOCH 3 . The crystal and molecular structure have been determined by the low temperature X-ray diffraction technique. The compound crystallizes in space group P 2 1 / c of the monoclinic system with a = 19.397(7), b = 10.891(7), c = 24.302(8) A, β = 108.95(2)° and Z = 4. With use of 2647 reflections ( I )>2.5σ( I )) the structure was refined to R ( R w ) = 0.045(0.036). The cluster Mo 2 Fe 2 S 4 (S 2 CNEt 2 ) 5 has a cubane-like skeleton [Mo 2 Fe 2 S 4 ] 5+ . Each metal atom is coordinated by three μ 3 -S atoms and a disulfide chelate terminal ligand. The fifth S 2 CNEt 2 group as a bridging ligand coordinates to two Mo atoms. In a molecule of the compound, the two Mo atoms are equivalent but the two Fe atoms are unequivalent.

Coordination Chemistry and Structure Characterization of C18H36O6N2Eu2(NO3)6·H2O

Abstract: The crystal structure of a cryptate complex of europium, C18H36O6N2Eu2(NO3)6·H2O, has been determined from three-dimensional single-crystal X-ray diffraction data collected on a computer-automated diffractometer. The compound crystallizes in the triclinic space group P l with unit cell dimensions a = 14.815(5), b = 8.828(2), c = 13.302(4) A, α = 91.57(2), β = 92.64(3), γ = 86.90(3)° and Z = 2. The structure was solved by a heavy atom method and refined by a blocked-matrix least-squares procedure to a conventional R index of 0.029 for 5422 reflections. The molecule is composed of cations (C18H36O6EuNO3)2+ and anions [Eu(NO3)5· H2O]2−. In the cation, the europium(III) ion enclosed in a [2.2.2] molecule is coordinated with eight oxygen and two nitrogen atoms, forming a 10-coordinate complex ion (cryptate), while the other europium(III) ion is bonded to eleven oxygen atoms in the anion.

Heterodimetallic Chalcogen‐Bridged Cubane‐Type Clusters of Molybdenum and Tungsten Containing First‐Row Transition Metals

Abstract: Transition metal cluster chalcogenides with cubane-type structures are relevant to our understanding of several industrial and biological catalytic processes. Recent advances in cluster chemistry owe much to the development of rational synthetic approaches, an aspect that is emphasised in this review which focuses on cuboidal clusters of molybdenum and tungsten (M) with M2M′2S4 and M3M′Q4 (Q = S, Se) central units that incorporate a first-row transition metal atom (M′). Special attention has been paid to the non-aqueous chemistry of these compounds. The structural features of these complexes are discussed in relation to their electronic structures within the framework of molecular orbital theory, spectroscopic, magnetic and electrochemical experimental data. Finally, the importance of these clusters in catalysis, nonlinear optics and in the formation of supramolecular adducts is discussed. (© Wiley-VCH Verlag GmbH & Co.
