Abstract

The structure of (1-phenyl-3-{2-[(2-aminoethyl)amino]ethylimino}-1-buten-1-olato-O,N, N’,N”)-copper(II) perchlorate, [Cu(baden)]ClO<sub>4</sub> was solved by Patterson and Fourier techniques and refined anisotropically to <i>R</i> = 0.066 for 2 205 unique observed reflections. The title complex (C<sub>14</sub>H<sub>20</sub>ClCuN<sub>3</sub>O<sub>5</sub>) crystallizes in the <i>P</i>2<sub>1</sub>/<i>c</i> space group with the lattice parameters <i>a</i> = 10.435(1), <i>b</i> = 20.745(2), <i>c</i> = 8.457(1) Å, β = 108.56(1)°, <i>Z</i> = 4. The complex cation including the baden ligand contains two five-membered and one six-membered chelate rings, and the phenyl ring. The perchlorate anion is disordered. Two perchlorate oxygen positions, O22A and O33B, each with one half occupation factor value and four N<sub>3</sub>O donor atoms from the baden ligand complete the coordination geometry about the Cu atom on the square pyramid [Cu-O22A = 2.655(11)Å and Cu-O33B = 2.855(10)Å]. Weak hydrogen bonds among cations and anions were found in the structure.
