Two new 1D coordination polymers: syntheses, structures and properties

Abstract

Two new coordination polymers, namely, [Zn(bi)(Cl)₂]_n (1) and [Cu(L)₂(bib)(H₂O)₂]_n (2) (bi = 4,4'-bis(2-methylimidazol-1-ylmethyl)biphenyl; L = 4-(2-(4-(methoxycarbonyl)phenoxy)ethoxy)benzoic acid and bib = 2,3-bis(4-pyridyl)butane), are synthesized and characterized. Both of 1 and 2 have 1D covalent chains, which show different conformally chain feature. 2D supremolecular rhombic and rectangle motifs are observed in 1 and 2, respectively. The O–H···O and C–H···Cl hydrogen-bonding interactions play a significant role in promoting the diversity of structural patterns.
