<P>A bispidine-like ligand involving four pyridine-N and three aliphatic-N donor atoms forms a bimetallic species with CuCl<SUB>2</SUB> in which all seven N-donors are bound and which aggregates in the crystal through double chloride-bridging to give a tetranuclear unit. The magnetism of this solid can be interpreted in terms of a relatively weak antiferromagnetic coupling between the two Cu(<SMALL>II</SMALL>) centres of the dinuclear subunits and a strong ferromagnetic coupling of the Cu(<SMALL>II</SMALL>) centres in different dinuclear units involved in the bis-chlorido bridge. In solution, the assembly decays into the dinuclear subunits and, in agreement with the solid state studies, the interaction between the corresponding Cu<SUP>II</SUP> centres is shown to be primarily due to dipole–dipole coupling.</P>
