One novel cobalt coordination polymer, {[Co(HTCB)(4,4'btb)]'HzO}n (1, H3TCB = 1,3,5-tris(4-carboxyphenyl)benzene, 4,4'-btb = 4,4'-bis(1,2,4-triazol-3-yl)biphenyl), has been synthesized and characterized ... One novel cobalt coordination polymer, {[Co(HTCB)(4,4'btb)]'HzO}n (1, H3TCB = 1,3,5-tris(4-carboxyphenyl)benzene, 4,4'-btb = 4,4'-bis(1,2,4-triazol-3-yl)biphenyl), has been synthesized and characterized by elemental analysis, IR, powder X-ray diffraction (PXRD), and thermogravimetric (TG) analyses. X-ray diffraction analysis reveals that complex 1 is a 2D 2-fold interpenetrated {44,62}-sql [Co(HTCB)(4,4'-btb)] sheet based on the 1D [Co(HTCB)]n chains and 1D [Co(4,4'-btb)]n chains. The crystal of 1 crystallizes in triclinic, space group P1 with a = 9.529(12), b = 13.914(16), c = 14.906(17) A, V= 1903(4) A3, Z = 2, C45H34N6CoO71 Mr= 829.71, Dc = 1.448 g/cm3, F(000) = 858 andμ(MoKa) = 0.514 mm-1. The final R = 0.0655 and wR = 0.1136 for 6603 observed reflections with 1 〉 2a(/) and R = 0.1136 and wR = 0.1747 for all data. 展开更多

Three new different dimensional coordination polymers, namely, [Zn(BA-)2(4,4?-bib)-1.5]n(1), [Zn(4-Br BA-)2(1,4-bmb)]n(2) and [Mn(4-Br BA)2(4,4?-bib)]n(3) have been assembled through the mixed-liga... Three new different dimensional coordination polymers, namely, [Zn(BA-)2(4,4?-bib)-1.5]n(1), [Zn(4-Br BA-)2(1,4-bmb)]n(2) and [Mn(4-Br BA)2(4,4?-bib)]n(3) have been assembled through the mixed-ligand synthetic strategy(4-HBr BA = 4-bromobenzoic acid, HBA = benzoic acid, 1,4-bmb = 1,4-bis(1 H-imidazol-4-yl)benzene, 4,4?-bib = 4,4?-bis(imidazolyl)biphenyl). Their structures have been determined by single-crystal X-ray diffraction analyses and further characterized by elemental analyses(EA), powder X-ray diffraction(PXRD), and thermogravimetric(TG) analyses. Single-crystal X-ray diffraction analysis reveals that the crystals of complexes 1~3 are all in triclinic systems, space group P1. Complexes 1 and 2 are 0D binuclear structures, and 3 is a 1 D chain. Moreover, the solid state fluorescence properties of 1 and 2 have been investigated. 展开更多
