A novel copper oxalate, Na2Cu(C2O4)2

The authors thank the Royal Society for the award of a Newton Fellowship (NF140881) to W.Y.A novel copper oxalate Na2Cu(C2O4)2 was synthesized through a hydrothermal method and characterized by single-crystal X-ray diffraction. It crystallizes in monoclinic system, P21/n space group with a = 72578(3) Å, b = 5.7711(4) Å, c = 8.6604(8) Å, β = 106.948(9)°. The structure displays a novel stacking pattern of [Cu(C2O4)2]2– units connected through electrostatic attraction by Na+ cations. Structural comparisons are made to related compounds.PostprintPeer reviewe

Tris(2-amino-1,3-thia­zolium) hydrogen sulfate sulfate monohydrate

The centrosymmetric crystal structure of the novel semi-organic compound, 3C3H5N2S+·HSO4 −·SO4 2−·H2O, is based on chains of alternating anions and water mol­ecules (formed by O—H⋯O hydrogen bonds). The chains are inter­connected with the 2-amino-1,3-thia­zolium cations via strong N—H⋯O and weak C—H⋯O hydrogen-bonding inter­actions into a three-dimensional network

2-Amino-1,3-thia­zolium dihydrogen phosphate

In the title compound, C3H5N2S+·H2PO4 −, the dihydrogen phosphate anions form infinite chains along [001] via short O—H⋯O hydrogen bonds. The 2-amino­thia­zolium cations inter­connect these chains into a three-dimensional network by short linear or bifurcated N—H⋯O and weak C—H⋯O hydrogen bonds

Coordination Mode

A novel Cu(II) coordination polymer of general empirical formula {[Cu(mu-HC(2)O(4))(2)(H(2)O)(2)][Cu(HC(2)O(4))(2)]a (TM) 6H(2)O} (n) (1) has been synthesized and characterized by single-crystal X-ray diffraction technique. The complex (1) crystallizes in the triclinic form with P-1 space group. It is quite surprising that single crystal X-ray analysis of 1 illustrates the presence of hydrogen oxalate ligand in the coordination environment of Cu(II) ion. Because oxalate is not present in the starting reaction mixture, it may be derived from the reduction of squarate ligand. In 1, Cu(II) ions exhibit two different coordination environments, forming a distorted octahedral geometry. The Cu1 is coordinated with six oxygen atoms from two bidentate HC(2)O(4) (-) and two aqua ligands, while Cu2 is coordinated with six oxygen atoms from four HC(2)O(4) (-) ligands. The HC(2)O(4) (-) ligand acts in two different coordination modes, as a bidentate and an unprecedented tridentate bridging coordination mode

A three-dimensional silver(I) framework assembled from 3,3 '-thiodipropionate: Synthesis, structure and molecular simulations for hydrogen gas adsorption

Arici, Mursel/0000-0001-8527-1587; keskin, seda/0000-0001-5968-0336; YESILEL, Okan Zafer/0000-0002-2284-1578; TAS, MURAT/0000-0002-2879-6501WOS: 000309627000015A novel three dimensional Ag(I)-3,3'-thiodipropionate metal organic framework, [Ag-2(mu(8)-tdp)](n) (1) (tdpH(2) = 3,3'-thiodipropionic acid), was synthesized and structurally characterized by FT-IR and photoluminescence spectroscopy, single crystal X-ray diffraction techniques and thermal analysis (TG, DTG and DTA). The compound crystallized in the monoclinic crystal system with the space group C2/c. The X-ray crystallographic study of 1 shows a short Ag center dot center dot center dot Ag contact with a distance of 3.022 angstrom. The most striking feature of 1 is that it exhibits a 3D porous framework with 1D infinite channels, and complex 1 exhibits strong fluorescent emission bands in the solid state at room temperature. Moreover, atomically detailed simulations were used to assess the potential of the complex for H-2 storage applications. (C) 2012 Elsevier Ltd.
