Crystal structure of aqua(perchlorato)bis[μ-(E)-2-({[2-(pyridin-2-yl)ethyl]imino}methyl)phenolato-κ 4 N, N ′, O: O ]dicopper(II) perchlorate

Abstract

The title compound, [Cu 2 (ClO 4)(C 14 H 13 N 2 O) 2 (H 2 O)]ClO 4, crystallizes as an unsymmetrical dinuclear cation bridged by the phenoxy O atoms with one Cu II atom coordinated by a water molecule and the other by a perchlorate anion, thus making both Cu II atoms five-coordinate, and with a further perchlorate anion present for charge balance. A long interaction [2.9893(5)Å] between one of the two Cu II atoms and an O atom of the perchlorate counter-ion links the cations and anions into linear chains along the a-axis direction. In addition, the water H atoms link with the perchlorate counter-ion. These interactions, along with numerous C - H⋯O interactions between the tetrahedral perchlorate anions, link the ions into a complex three-dimensional array. One of the perchlorate anions is disordered over two conformations with occupancies of 0.586(4) and 0.414(4).
