Abstract
The title compound, [Cu2(ClO4)(C14H13N2O)2(H2O)]ClO4, crystallizes as an unsymmetrical dinuclear cation bridged by the phen-oxy O atoms with one CuII atom coordinated by a water mol-ecule and the other by a perchlorate anion, thus making both CuII 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 CuII 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 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).

Summary
Proteins containing dinuclear copper centers play important roles in biology, including dioxygen transport or activation, electron transfer, reduction of nitrogen oxides and hydrolytic chemistry (Karlin & Tyeklar, 1993; Torelli et al, 2000; Poater et al, 2008; Utz et al, 2003). Compounds of transition metal complexes comprising the ({[2-(pyridin-2-yl)ethyl]imino}methyl)phenol ligand have been synthesized for various processes (Egekenze et al, 2017; Sanyal et al, 2014; Chakraborty et al, 2013; Tandon et al, 1994, 2000; Latour et al, 1989). Pyrazole and pyridine are nitrogen donors that are commonly used as ligands to mimic metalloenzymes. These heterocyclic groups are widely used to form inorganic complexes because they have pKa values similar to those present in the hystidyl functional group of many enzymes.
