摘要：

Interactions between metal ion complexes in the compounds Delta-[Cr(en)(3)]Delta-[Cr(ox)(3)] and Delta-[Co(en)(3)]Delta-[Cr(ox)(3)] have been investigated by X-ray crystallography and magnetic susceptibility measurements. Crystals of both compounds are hexagonal and are isostructural with the known Delta-[Co(en)(3)]Delta-[Rh(ox)(3)] [Inorg. Chem. 30 (1991) 4954] with chains of alternating anions and cations parallel to the crystallographic c-axis. The susceptibility behavior suggests that magnetic interactions are stronger in Delta-[Cr(en)(3)]Delta-[Cr(ox)(3)] where both anion and cation are paramagnetic than in A-[Co(en)3]A-[Cr(OX)31 where only the anion is paramagnetic. Single crystal studies with the former compound reveal that magnetic interactions along the c-axis chains, where the Cr-Cr distances are shortest, are weaker than those involving off-axis interactions. Magnetic measurements were also made on [Cr(en)(2)(ox)][Cr(en)(ox)(2)] . 2H(2)O. The structure of this compound has been previously reported, (C) 2001 Elsevier Science B.V. All rights reserved.
