Diaqua-sodium(I) perchlorate bis-[?-2-(carboxyl-atomethyl-imino-meth-yl)phenolato]bis-[(3-methyl-pyridine)copper(II)].

ABSTRACT: In the title compound, [Na(H(2)O)(2)]ClO(4)·[Cu(2)(C(9)H(7)NO(3))(2)(C(6)H(7)N)(2)], the Cu(II) atom is coordinated by one N atom and two O atoms from a tridentate N-salicylideneglycinate Schiff base dianion and one N atom from a 3-methyl-pyridine ligand. Longer Cu?O contacts [2.680?(2)?Å] complete an approximate square-based pyramidal coordination geometry around Cu(II), forming a dimeric complex across a centre of inversion. The dimeric complexes form stacks along the a axis, with Cu?O contacts of 3.332?(2)?Å between them. The Na(+) cations and perchlorate anions lie on twofold rotation axes between the stacks. The former are coordinated by two disordered water mol-ecules (each with half-occupancy), and form Na?O contacts of 3.698?(3)?Å to the perchlorate anions and Na?? contacts to neighbouring salicylideneglycinate ligands [shortest Na?C = 3.516?(3)?Å].
