AbstractA new bis(carbon dioxide) adduct of molybdenum containing the tridentate, bis(phosphine) ligand, HN(CH2CH2PMe2)2 (NP2), in a mer conformation has been synthesized and structurally characterized. Its carbonyl carbonate isomer [Mo(CO3)(CO)(NP2)(PMe3)] has also been prepared. In addition, the reactivity of the complex [Mo(CO3)(CO)(PMe3)4] toward CO has been studied, a transformation that has led to the formation of the dicarbonyl complex [Mo(CO3)(CO)2(PMe3)3]. This complex liberates CO2 upon heating under a carbon monoxide atmosphere by means of a CO–CO3 conproportionation reaction. The new trinuclear complex [Mo3(μ2-CO3)(μ2-O)2(O)2(CO)2(H2O)(PMe3)6]·H2O, resulting from the interaction of [Mo(CO3)(CO)(PMe3)4] and water, has been isolated and structurally characterized.
