Aqua(3,5-dimethylpyrazole-N1)(N-salicylideneglycinato-O,N,O′)copper(II), [Cu(C9H7NO3)(C5H8N2)(H2O)], adopts a square-pyramidal CuII coordination with the tridentate N-salicylideneglycinato Schiff base dianion and the 3,5-dimethylpyrazole ligand bound in the basal plane. The water molecule occupies the apical site. The complex molecules are arranged in four magnetically non-equivalent orientations, two at a time forming zigzag chains. Both the interchain CuCu spacing of 7.396 Å and the intrachain CuCu distance of 6.880 Å are too large for effective dipolar coupling between the paramagnetic CuII centres, in agreement with the results of electron paramagnetic resonance (EPR) spectroscopy.
