title: Bis{2-[2-(isopropyl-ammonio)ethyl-imino-meth-yl]-5-methoxy-phenolato}copper(II) bis-(perchlorate).
abstract: In the title compound, [Cu(C(13)H(20)N(2)O(2))(2)](ClO(4))(2), the Cu(II) atom in the complex dication is chelated by two phenolate O atoms and two imine N atoms from two zwitterionic 2-[2-(isopropyl-ammonio)ethyl-imino-meth-yl]-5-methoxy-phenolate ligands, forming a distorted square-planar geometry. One of the perchlorate anions is disordered over two sites with occupancies of 0.611 (15) and 0.389 (15). Intra-molecular N-H⋯O hydrogen bonds are observed in the complex dication. In the crystal structure, the perchlorate anions are linked to complex dications by inter-molecular N-H⋯O hydrogen bonds.
