Reactivity of carbonyl complexes containing MoHg bonds; reaction of tin(II) halides with [Mo(CO)3(NN)(HgX)(X)] (NN = bpy, phen, dmp); crystal structure of [Mo(CO)3(dmp)(HgCl)(Cl)]
摘要:
Reaction of HgCl2 with [Mo(CO),(dmp)] (dmp = 2,9-dimethyl-1,10-phenanthroline) gives the heterobimetallic compound [MO(CO)3(dmp)(HgCl)(Cl)] (I), which gives rise to a new compound [Mo(CO)3(dmp)(HgCl)(Cl)] . 1/2(CH3)2CO (II) in acetone solution at low temperature. The crystal structure of I has been solved and the compound shown to be a capped trigonal prism containing Mo-Hg-Cl and Mo-Cl bonds. The reactions of the above and related heteronuclear complexes [MO(CO)3(NN)(HgX)(X)] [X = Cl, Br; NN = 2,2'-bipyridine (bpy), 1,10-phenanthroline (phen)] with tin (II) halides were studied. No insertion of the latter into the metal-metal or metal-halogen bonds were observed, with only bimetallic tricarbonyl complexes containing Mo-Hg bonds being isolated.
