| Abstract: | Five new coordination polymers, namely, [Ni2(L)2(4, 4′‐bipy)3)] · H2O]n ( 1 ), [Ni2(L)2(O) (bpp)2]n ( 2 ), [Zn(L)(bib)0.5]n ( 3 ), [Zn(L)(PyBIm)]n ( 4 ), and [Zn3(L)2(OH)(im)]n ( 5 ) [H2L = benzophenone‐2, 4′‐dicarboxylic acid, 4, 4′‐bipy = 4, 4′‐bipyridine, bpp = 1, 3‐bis(4‐pyridyl)propane, PyBIm = 2‐(4‐pyridyl)benzimidazole, and im = imidazole] were synthesized under hydrothermal conditions. Structure determination revealed that compound 1 is a 3D network and exhibits a 4‐connected metal‐organic framework with (42.63.8) topology, whereas compounds 2 , 3 , 4 , and 5 are two‐dimensional layer structures. In compounds 2 – 4 , dinuclear metal clusters are formed through carboxylic groups. In compound 5 , trinuclear metal clusters are formed through μ3‐OH and carboxylic groups. The carboxylic groups exhibit three coordination modes in compounds 1 – 5 : monodentately, bidentate‐chelating, and bis‐monodentately. Furthermore, the luminescent properties for compounds 3 , 4 , and 5 were investigated. |
