Aqua[4-(hydroxyiminomethyl)pyridine-κN1](iminodiacetato-κ3O,N,O′)copper(II)

Abstract

In the title complex, [Cu(C4H5NO4)(C6H6N2O)(H2O)], conventionally abbreviated Cu(IDA)(4-OXPy)(H2O), where IDA is imino­diacetate and 4-OXPy is 4-(hy­droxy­imino­meth­yl)pyridine, the CuII atom exhibits a distorted square-pyramidal coordination geometry, which is constructed from two O atoms and one N atom from a IDA ligand, one N atom from 4-OXPy ligand and one O atom from water. This mol­ecule looks like a space shuttle, the IDA ligand is its empennage (tail), and the 4-OXPy ligand is its airframe. The complexes are linked into two-dimensional supra­molecular layers parallel to (100) by three pairs of O—H⋯O hydrogen bonds. Two pairs of N—H⋯O hydrogen bonds further connect these supra­molecular layers, forming a three-dimensional supra­molecular network.
