Metallophilic interactions and magnetism in heterobimetallic {Pt,M} lantern complexes

Three polymeric heterobimetallic {Pt,M} lantern chains have been synthesized with DABCO, along with the discrete molecular analog of each with quinuclidine. Measurements of the temperature dependence of the magnetic susceptibility of M = Co and Ni chains reveal antiferromagnetic exchange coupling between the 3d metal centers with J = −10 cm−1 for the Co-containing compound and J = −32 cm−1 between Ni centers in the other, both of which access the Pt…Pt metallophilic interactions.
