3-Hexyne complexes of molybdenum(II) and tungsten(II). Crystal structures of [WI2(CO)(PPh3)2(η2-EtC 2Et)] and [WI2(CO){Ph2P(CH2)3PPh 2}(η2-EtC2Et)]

Treatment of [MI2(CO)3(NCMe)2] (M = Mo, W) with two equivalents of EtC2Et in CH2Cl2 at 0°C yields the bis(3-hexyne) complexes [MI2(CO)(NCMe)(η2-EtC2Et)2] (1 and 2). Complexes 1 and 2 react with two equivalents of PPh3 in CH2Cl2 to give the complexes [MI2(CO)(PPh3)2 (η2-EtC2Et)] (3 and 4). The molecular structure of 4 (M = W) has been crystallographically determined and has a pseudo-octahedral geometry with the two PPh3 ligands trans to each other with the two cis-iodo-ligands, which together with the carbonyl and 3-hexyne ligand are occupying the equatorial plane. Reaction of 1 and 2 with an equimolar amount of Ph2P(CH2)nPPh2 (for M = Mo, n = 1; for M = W, n = 1 to 6) in CH2Cl2 affords the mono(3-hexyne) complexes [MI2(CO){Ph2P(CH2)nPPh 2}(η2-EtC2Et)] (5 - 11). The tungsten complex [WI2(CO){Ph2P(CH2)3PPh 2}(η2-EtC2Et)] (8) has also been crystallographically characterised and has cis-phosphorus atoms in the equatorial plane with the carbonyl and one of the iodo-ligands, with the other iodo-ligand and the 3-hexyne occupying the axial sites.
