Abstract

Reactions between the bulky ligand tris(2,4,6-trimethoxyphenyl)phosphine (TMPP) and HgX2 (X = Cl, Br, 1) in ethanol have been described. Complexes of stoichiometry (P:Hg) 1:1, 2:1 and 2:3 have been isolated and their spectral features discussed. The structures of the 1:1 bromide and iodide show them to be discrete monomers unlike most other tertiary phosphine analogues. Additionally a complex of stoichiometry TMPP(HgI2)(2) has been prepared and characterised structurally as (TMPP)HgI(mu-I)HgI(mu-I)(2)HgI(mu-I)HgI(TMPP).
