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.

The reactions of tricarbonylphosphine complexes (bipy)(P)Mo(CO)3, (bipy)= 2,2′-bipyridine and (P) = P(4-ClC6H4)3, P(4-FC6H4)3, P(4-CH3C6H4)3 and P(4-CH3OV6H4)3, with HgCl2 give compounds of the type (bipy)2Mo2(CO)6·HgCl2 and (bipy)Mo(CO)3(HgCl)(Cl), depending on the mol ratio of reactants employed. The reaction proceeds with elimination of the phosphine ligand and the coordination of HgCl2 to molybdenum
