The trinuclear title compound, [Co(3)(CH(3)COO)(4)(C(20)H(22)N(2)O(6))(2)]·2CH(2)Cl(2), contains mixed-valence cobalt ions in the following order Co(III)-Co(II)-Co(III) where all the three cobalt ions are hexa-coordinated. The central cobalt ion is situated on an inversion centre and is in an all-oxygen environment, coordinated by four phenolate O atoms and two O atoms from bridging acetate groups, while the terminal cobalt ion is hexa-coordinated by two phenolate O atoms, two acetate O atoms and two imine N atoms. This complex contains a high-spin central Co(II) and two terminal low-spin Co(III)i.

[2-({3-[(3-Amino-prop-yl)amino]-prop-yl}imino-meth-yl)phenolato-κO,N,N'',N''']bromidocopper(II).

In the title compound, [Cu(C(13)H(20)N(3)O)Br], the Cu(II) atom is coordinated by three N atoms and one O atom from the deprotonated ligand derived from the Schiff base condensation of 3,3-imino-bis-(propyl-amine) and salicyl-aldehyde. The three N and the O atoms occupy equatorial positions, while the Br atom occupies an axial position. The amine H atoms form inter-molecular hydrogen bonds with the Br and O atoms of adjoining mol-ecules.

In the crystal of the dinuclear title compound, [Cu(2)(C(13)H(13)N(2)O)(2)(ClO(4))(2)]·2CH(3)CN, the two bridging perchlorate ions chelate to the two Cu(II) atoms in a μ-O:O' fashion on opposite sides of the equatorial plane. The Cu(II) ions display a distorted octa-hedral coordination geometry (in the usual 4 + 2 Jahn-Teller arrangement), each being coordinated by two O atoms from the two perchlorate ligands, and two N and O atoms from the reduced Schiff base ligand. The asymmetric unit contains two acetonitrile solvent mol-ecules.
