Treatment of [MBr2(CO)3(NCMe)2] (M = Mo or W) with a slight excess of RS(CH2)2SR (R = Ph, C6H4F-4) in CH2Cl2 at room temperature gave the acetonitrile displaced products [MBr2(CO)3{RS(CH2)2SR-S,S′}]. The complex with M = W, R = Ph was crystallographically characterised and has a distorted capped octahedral geometry with one carbonyl group in the capping position, two carbonyls and one sulfur atom in the capped face, and one sulfur and two bromines in the uncapped face. Reaction of [WBr2(CO)3(NCMe)2] with two equivalents of RS(CH2)2SR in CH2Cl2 at room temperature gives the cationic complexes [WBr(CO)3{RS(CH2)2SR-S}{RS(CH2) 2SR-S,S′}]Br. Similarly, treatment of [WBr2(CO)3(NCMe)2] with one and two equivalents of Ph2P(S)CH2P(S)Ph2 in CH2Cl2 at room temperature afforded [WBr2(CO)3{Ph2P(S) CH2P(S)Ph2-S,S′}] and [WBr(CO)3{Ph2P(S)CH2P(S)Ph2-S} {Ph2P(S)CH2P(S)Ph2-S,S′}]Br respectively. Reaction of [MBr2(CO)3(NCMe)2] with one equivalent of MeS(CH2)2S(CH2)2SMe in CH2Cl2 at room temperature gave [MoBr2(CO)2{MeS(CH2)2S(CH 2)2SMe-S,S′,S″}] and [WBr2(CO)3{MeS(CH2)2S(CH 2)2SMe-S,S′}] respectively. Finally, reaction of equimolar quantities of [MoBr2(CO)2(NCMe)2] and ttob (ttob = 2,5,8-trithia[9]-o-benzenophane) gives the S3 bonded complex [MoBr2(CO)2(ttob-S,S′,S″)].
