(2-Formyl-6-methoxy-phenolato-κ2 O 1,O 2)(perchlorato-κO)(1,10-phenanthroline-κ2 N,N′)copper(II)

Abstract

In the title mol-ecule, [Cu(C8H7O3)(ClO4)(C12H8N2)], the CuII ion is five-coordinated by two N atoms [Cu - N = 1.995 (3) and 2.022 (3) Å] from a 1,10-phenanthroline ligand, two O atoms [Cu - O = 1.908 (2) and 1.927 (2) Å] from an o-vanillin ligand and one O atom [Cu - O = 2.510 (3) Å] from a perchlorate anion in a distorted square-pyramidal geometry. Three O atoms of the perchlorate anion are rotationally disordered between two orientations, with occupancies of 0.525 (13) and 0.475 (13). In the crystal structure, two mol-ecules related by a centre of symmetry are paired in such a way that the phenolate O atom from one mol-ecule completes the distorted octa-hedral Cu coordination in another mol-ecule [Cu⋯O = 2.704 (2) Å].
