Crystal structure of aqua(perchlorato)bis[μ-(E)-2-({[2-(pyridin-2-yl)ethyl]imino}methyl)phenolato-κ4N,N′,O:O]dicopper(II) perchlorate

Abstract

The title compound, [Cu2(ClO4)(C14H13N2O)2(H2O)]ClO4, crystallizes as an unsymmetrical dinuclear cation bridged by the phenoxy O atoms with one CuIIatom coordinated by a water molecule and the other by a perchlorate anion, thus making both CuIIatoms five-coordinate, and with a further perchlorate anion present for charge balance. A long interaction [2.9893 (5) Å] between one of the two CuIIatoms and an O atom of the perchlorate counter-ion links the cations and anions into linear chains along thea-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).
