Crystal structures of [WI2(CO)3{Ph2P(CH2)nPPh2}] (n = 2 or 3)

Abstract

[WI2(CO)3{Ph2P(CH2)2PPh2}] (1) crystallizes out in the monoclinic space group P21/n, with a = 13.852(7) A, b = 14.789(19) A, c = 14.915(19) A, β = 102.86(1)°, Z = 4. [WI2(CO)3{Ph2P(CH2)3PPh2}] (2) crystallizes out in the monoclinic space group P21/n, with a = 10.499(15) A, b = 14.58(2) A, c = 20.75(3) A, β = 103.59(1)°, Z = 4. Both structures show the metal in a seven-coordinate environment with a carbonyl in the unique capping position, two further carbonyls and a phosphorus in the capped face, and two iodides and the second phosphorus in the uncapped face.
