摘要：
Aqua(3,5-dimethylpyrazole-N-1)(N-salicylideneglycinato-O,N, O')copper(II), [CU(C9H7NO3)(C5H8N2)(H2O)], adopts a square-pyramidal Cu-II 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 Cu...Cu spacing of 7.396 Angstrom and the intrachain Cu...Cu distance of 6.880 Angstrom are too large for effective dipolar coupling between the paramagnetic Cu-II centres, in agreement with the results of electron paramagnetic resonance (EPR) spectroscopy.
