A new organic-inorganic hybrid compound constructed from [Mn 2 V 22 O 64 ] 10 − units, H 6 [(C 6 H 4 NO 2 Cu(H 2 O) 4 )] 2 [Mn 2 V 22 O 64 ]·28H 2 O 1 , has been synthesized and characterized by single-crystal X-ray diffraction, IR, powder X-ray diffraction (XPRD) and TG. Compound 1 is composed of dimeric [Mn 2 V 22 O 64 ] 10 − polyoxoanions, metal-organo fragments [(C 6 H 4 NO 2 Cu(H 2 O) 4 )] 2 + and lattice water molecules. Moreover, a three-dimensional supramolecular structure is formed in 1 by the extensive hydrogen bond interaction among the terminal oxygen atoms of [Mn 2 V 22 O 64 ] 10 − anions, the coordinated waters of Cu 2 + ions and crystal water molecules. Compound 1 exhibits remarkable catalytic activity for the heterogeneous oxidation of sulfides under mild condition. [ABSTRACT FROM AUTHOR]

Two new homometallic coordination polymers 1 and 2 have been prepared by the directly one-step hydrothermal reactions of a carboxylate-functionalized salen ligand with Zn(II) and Co(II) ions, respectively. 1 exhibits a 3D open framework built by [Zn 4 (μ 4 -O)(carboxylate) 8 ] units and double Zn-salen ligands, while 2 shows a 1D chain structure constructed by cobalt ions and the ligand derived from the hydrolysis to one C N bond of salen ligand. The preliminary fluorescence measurements of 1 – 2 show the influence of structure on the property. [ABSTRACT FROM AUTHOR]
