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)]ClO4 was solved by Patterson and Fourier techniques and refined anisotropically to R = 0.066 for 2 205 unique observed reflections. The title complex (C14H20ClCuN3O5) crystallizes in the P21/c space group with the lattice parameters a = 10.435(1), b = 20.745(2), c = 8.457(1) Å, β = 108.56(1)°, Z = 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 N3O 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.
