Reaction of equimolar amounts of [WI2(CO)3(NCMe)2] and norbornadiene (nbd) in toluene at 95°C for 3h gave the 16-electron crystallographically characterised complex, [WI2(CO)2(nbd)] (1) in 96% yield. The structure of 1 has a distorted octahedral geometry, with the two cis- iodo ligands opposite to the two alkene groups in the equatorial plane, with the carbonyl groups in the axial sites. Treatment of 1 with two equivalents of PhC2Ph in CH2Cl2 at room temperature afforded the bis(alkyne) complex [WI2(CO)2(η2-PhC2Ph) 2] (2). Equimolar quantities of 1 and 4,4′-bipyridine react in CH2Cl2 at room temperature to yield the seven-coordinate complex, [WI2(CO)2(4,4′-bipyridine)(nbd)] (3).
