摘要：

The thioethereal mercury complexes [N(CH2CH2SCHMe2)(3)HgX](2)(Hg2X6) (X = Cl, Br) have been prepared by reaction of HgX2 with the tripodal ligand N(CH2CH2SCHMe2)(3). The chloro derivative has been fully characterized by a crystal structure determination: space group P (1) over bar, a = 10.114(2), b = 11.230(5), c = 12.196(7) Angstrom, alpha = 86.11(4), beta = 73.47(4), gamma = 74.45(4)degrees, Z = 2. The complex shows a geometry intermediate between the trigonal bipyramidal and the tetrahedron, These distortions have been compared with those found in a series of mercury complexes [LHgX](+) containing the ligand tris (2-diphenylphosphinoethyl)amine, np(3), or tris(2-dimethylaminoethyl)amine, Me(6)tren, the differential weakening of the apical N-Hg bond being related to the electronegativity and to the sigma-bonding capability of the ligand trans to the apical nitrogen.
