Abstract

To understand the influence of the ligand on crystal growth, two new polycarboxylate ligands, 2-(carboxyphenyl)iminoacetic propanoic acid (H 3cpiap) and 2-(carboxyphenyl)iminodipropanoic acid (H 3cpidp), have been synthesized. The reaction of each with Cu(NO 3)2·3H2O under similar reaction conditions yields two 1D coordination polymers {[Cu3(cpiap) 2(H2O)3](-H2O)}n· 7nH2O (1) and [Cu(H2cpidp)2(H 2O)2]n·4nH2O (2), respectively. A T5(2) 1D water tape constructed from an edge-sharing cyclic pentamer has been observed in compound 1, in which the water chains interact with the 1D coordination polymer chains to form a 3D supramolecular binodal (5,8)-network through hydrogen-bonding interactions.
