One-Dimensional Chain Copper(II) and Nickel(II) Coordination Polymers With N-Salicylideneglycine Schiff Base Ligand

[Cu(Sal-Gly)(Im)(H2O)] (1) and [Ni(Sal-Gly)(H2O)2] (2) (Sal-Gly = N-salicylideneglycinate) was synthesized and structurally characterized. 1 and 2 are one-dimensional chain coordination polymers. In 1, Cu(II) ion has a five-coordinated square-pyramidal geometry and is surrounded by two O and one N atoms from a tetradentate Sal-Gly dianion and one N atom from imidazole ligand and one O from adjacent Sal-Gly ligand. In 2, Ni(II) adopts six-coordinated distorted octahedral geometry and is surrounded by two O and one N atoms from a tetradentate Sal-Gly dianion, two O from two aqua ligands, and one O from adjacent Sal-Gly ligand.
