The variation of magnetic susceptibility with temperature for a number of binuclear halide complexes of molybdenum of formula A3IMo2X9 (A = Cs, Et4N, Et3NH; X = Cl, Br) has been studied over the range 90-400°K. The magnetic behaviour is consistent with that expected for magnetically isolated exchange-coupled pairs of molybdenum atoms. The coupling is interpreted as occurring mainly by direct metal-metal interaction rather than superexchange.
