TL;DR: In this paper, a new nano-structured lead(II) coordination polymer, [Pb(μ-bpp)(μ-Br)2]n (PBB) [bpp] = 1,3-di(4-pyridyl)propane], has been synthesized by the reaction of a mixture lead( II) acetate and KBr with bpp by both hydrothermal and sonochemical methods.

TL;DR: This spray technique simplifies the nanosheet production process by industrialized means and enhances its controllability by the fast liquid-liquid interfacial fabrication, thus allowing access to the industrialized fabrication of MOF and ICP nanosheets.
Abstract: We have developed a rapid and convenient method for fabricating metal-organic framework (MOF) and infinite coordination polymer (ICP) nanosheets by spraying the atomized solution of metal ions onto the organic ligand solution. Nanosheet formation could be attributed to the anisotropic diffusion of metal ions in the ligand solution, which may give rise to a lateral interface of metal ions and organic ligands, where the crystals tend to grow laterally in the form of nanosheets. Three kinds of Zn- and Cu-based MOF nanosheets and two kinds of Co-based ICP nanosheets have been successfully obtained by spraying under mild conditions. The two-dimensional structures of nanosheets with a nanometer thickness and a homogeneous size can be evidenced by scanning electron microscopy, atomic force microscopy, X-ray diffraction, Brunauer-Emmett-Teller, and Fourier transform infrared spectroscopy measurements. Furthermore, the fabricated ICP nanosheets have exhibited efficient catalytic performance for the conversion of CO2 to high-value-added chemicals. This spray technique simplifies the nanosheet production process by industrialized means and enhances its controllability by the fast liquid-liquid interfacial fabrication, thus allowing access to the industrialized fabrication of MOF and ICP nanosheets.

TL;DR: The synthesis of four new oxo-centered Fe clusters (1 a-c, 2) of the form [Fe(III)3(mu3-O)(CH2=CHCOO)6] with acrylate as the bridging ligand gives rise to potentially intrinsically chiral oxe-centered {M3} trimers that show a tendency to spontaneously resolve upon crystallization.
Abstract: The synthesis of four new oxo-centered Fe clusters (1 a-c, 2) of the form [Fe(III)3(mu3-O)(CH2=CHCOO)6] with acrylate as the bridging ligand gives rise to potentially intrinsically chiral oxo-centered {M3} trimers that show a tendency to spontaneously resolve upon crystallization. For instance, 1 a, [Fe(III)3(mu3-O)(CH2=CHCOO)6-(H2O)3]+, crystallizes in the chiral space group P3(1) as a chloride salt. Crystallization of 1 b, [Fe3(mu3-O)(C2H3CO2)6(H2O)3]NO3 x 4.5 H2O, from aqueous solution followed by recrystallization from acetonitrile also gives rise to spontaneous resolution to yield the homochiral salt [Fe3(mu3-O)(C2H3CO2)6-(H2O)3]NO3 x CH3CN of 1 c (space group P2(1)2(1)2(1)). Furthermore, the reaction of 1 a with hexamolybdate in acetonitrile gives the helical coordination polymer {[(Fe3(mu3-O)L6(H2O))(MoO4)-(Fe3(mu3-O)L6(H2O)2)] x 2 CH3CN x H2O}infinity 2 (L: H2C=CHCOO), which crystallizes in the space group P2(1). The nature of the ligand geometry allows the formation of atropisomers in both the discrete (1 a-c) and linked {Fe3} clusters (2), which is described along with a magnetic analysis of 1 a and 2.

TL;DR: In this article, the first example of a coordination polymer structure consisting of one-dimensional polycatenanes fused via silver ions is described. But it is only a two-dimensional structure, and it can be derived from simple rings consisting of two silver ions and two ligand molecules.
