摘要

An unusual formate-bridged heterobimetallic binuclear Cr~(III)Mn~(III) porphyrin complex has been synthesized unexpectedly based on the building blocks K[Cr(bpb)(CN)2] [bpb~(2-) =1,2-bis(pyridine-2-carboxa-mido)benzenate] and [Mn(TClPPXH2O)2]ClO4 [H2TClPP = meso-tetra(4-chlorophenyl)porphyrin]. The complex with the formula [Cr(bpb)(CN)(CO2H)Mn(TClPP)(CH3OH)]·2CH3OH (1) has been characterized by elemental analysis, FT-IR and X-ray structure determination. The magnetic coupling between the Cr(III) and Mn(III) ions in the title compound was found to be antiferromagnetic with J_(MnCr)= -1.89(2) cm~(-1) on the basis of the Hamiltonian H = -2JS_(Cr)S_(Mn).
