New complexes of molybdenum and tungsten with dinitrogen and other small molecules, trans-[M(CO)3(PCy3)2L](L = N2, H2, C2H4, or SO2), have been synthesized by the reaction of [M(CO)3(cycloheptatriene)] with 2PCy3 in the presence of L; removal of L yields the formally five-co-ordinate species [M(CO)3(PCy3)2].
