The complex [MoCl(
3-allyl)(CO)2(dmpm)] (dmpm = bis(dimethylphosphino)methane) (1)reacts with sodium azide and with sodium cyanide to afford the new complexes [Mo(N3)(3-allyl)(CO)2(dmpm)] (2) and [Mo(CN)(3-allyl)(CO)2(dmpm)] (3), respectively, which werecharacterized spectroscopically and by X-ray diffraction. Complex 2 is a cis-dicarbonyl inwhich one of the P atoms of dmpm is approximately trans to a carbonyl, and the other istrans to the allyl. In contrast, 3 is a rare trans-dicarbonyl. A theoretical analysis was appliedto rationalize this difference.
