| Abstract: | WI2(CO)3{Ph2P(CH2)2PPh2}] (1) crystallizes out in the monoclinic space group P21/n, with a = 13.852(7) Å, b = 14.789(19) Å, c = 14.915(19) Å,  = 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) Å, b = 14.58(2) Å, c = 20.75(3) Å, = 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. |
