Treatment of [MI2(CO)3(NCMe)2] with two equivalents of P(OR)3 (for M=W only, R=Me, iPr; for M=Mo and W, R=Ph) in Et2O gave the bis(phosphite) complexes [MI2(CO)3{P(OR)3}2] (1-4) in high yield. The complex for M=W, R=iPr was crystallographically characterised, and has a distorted capped octahedral geometry with a phosphite group capping a tricarbonyl face. Reaction of [WI2(CO)3(NCMe)2] with three equivalents of P(OR)3 (R=Me, Et) in Et2O afforded the tris(phosphite) complexes [WI2(CO)2{P(OR)3}3], which was crystallographically characterised for R=Me. The structure of [WI2(CO)2{P(OMe)3}3] has an almost idealised capped trigonal prismatic geometry with a phosphite ligand capping a rectangular face containing C(1), C(2), I(2) and P(3).
