Abstract

In the title compound, [Rh(2)(C(8)H(15)N(3))(2)(C(8)H(12))(2)]Cl(2).CH(2)Cl(2).CH(3)OH, the dinuclear Rh(I) complex has C(2) symmetry and the two pyrazolato ligands act as mu-bridges. The coordination of each Rh(I) cation is completed by one cyclooctadiene (COD) ligand. It is shown that the average Rh-C(COD) distance is linearly dependent on the Rh-N(pyrazole) distance in this type of compound, and this is ascribed to the steric hindrance produced by the packing.
