Abstract

Complexes of the hydrotris(methimazolyl)borate ligand (Tm) have been prepared with zinc, cadmium and mercury halides. Complexes of type [M(Tm)X] were obtained and characterised by NMR and mass spectrometry, X-ray crystallographic analysis of [Zn(Tm)X] (X = Cl, Br, I) reveals a symmetrical coordination mode of the ligand, but no significant change with different halides, which sit on the approximate C-3 axes of the complexes, The structures of [M(Tm)Br] (M = Cd, Hg) are isomorphous with one another, Again, the ligand is symmetrically coordinated to the metal, but the halide is now significantly displaced from the approximate C-3 axis of the M(Tm) unit, resulting in what approximates to a trigonal pyramidal geometry. Unlike in most distorted mercury structures, little bond length expansion (towards two- or three-coordinate geometries) occurs. This is ascribed to the strong affinity of the thione donors for Hg.
