Crystal structure of aqua-(perchlorato)bis-[μ-()-2-({[2-(pyridin-2-yl)eth-yl]imino}-meth-yl)phenolato-κ,',:]dicopper(II) perchlorate.

The title compound, [Cu(ClO)(CHNO)(HO)]ClO, crystallizes as an unsymmetrical dinuclear cation bridged by the phen-oxy O atoms with one Cu atom coordinated by a water mol-ecule and the other by a perchlorate anion, thus making both Cu atoms five-coordinate, and with a further perchlorate anion present for charge balance. A long inter-action [2.9893 (5) Å] between one of the two Cu atoms and an O atom of the perchlorate counter-ion links the cations and anions into linear chains along the axis direction. In addition, the water H atoms link with the perchlorate counter-ion. These inter-actions, along with numerous C-H⋯O inter-actions between the tetra-hedral 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).
