Mercury(II) halide complexes of tertiary phosphines. Part XVII. Complexes of the very basic and sterically demanding ligand, tris(2,4,6-trimethoxyphenyl)phosphine (TMPP) of stoichiometry (TMPP)(x)(HgX2)(y) (X = Cl, Br, I; x=1, 2; y=1 : x=2, y=3 : X = I; x=1, y=2). Crystal structures of the monomeric 1 : 1 complexes (TMPP)HgX2 (X = Br, I) and (TMPP) (HgI2)(2)

Record type: Article

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).
