Multinuclear coordination polymers constructed from V-shaped multicarboxylate and bis(imidazol-1-ylmethyl)-benzene ligand: Syntheses, crystal structures, and luminescent properties

Five new coordination polymers [Cu(OBA)(1,2-bix)]n·nH2O (1), [Cu(1,4-bix) (O-OBA)]n (2), [Cd3(1,2-mbix)2(O-OBA)3]n·3nH2O (3), [Cu(1,2-bix) (H2ODPT)]n·2nH2O (4), [Cd4(ODPT)2(1,3-bix)2]n·2nH2O (5) (H2OBA = 4,4′-oxybis- (benzoic acid), O-H2OBA = 2,2′-oxybis(benzoic acid), H4ODPT = 4,4′-oxidiphtalic acid, 1, n-bix = 1, n-bis(imidazol-l-ylmethyl)benzene (n = 2, 3, 4), 1,2-mbix = 1,2-bis(2-methyl-imidazol-l-ylmethyl)benzene), have been synthesized.
