STRUCTURE OF METHYL(O-NITROBENZENETHIOLATO)MERCURY

摘要

The compound, MeHgSC6H4NO2-o, crystallizes in the monoclinic space group, P2(1) with Z = 8. In each of the two independent molecules of MeHgSC6H4NO2-o. there is a S---O intramolecular interaction [2.73(2) (molecule A) and 2.81(2) Angstrom (molecule B)] with the three nearest intermolecular neighbours to each Hg atom being 2 S and 1 O atoms: in molecule A, Hg---O = 3.48(2), Hg---S = 3.322(4) and 3.539(4) Angstrom; in molecule B, Hg---O = 3.61(3), Hg---S = 3.257(4) and 3.647(5) Angstrom. The geometry at Hg becomes trigonal bipyramidal if all three of these secondary contacts are included with the primary linear bonds [Hg-C = 2.08(2) and Hg-S = 2.379(4) Angstrom, C-Hg-S = 176.4(5)degrees in molecule A; Hg-C = 2.04(2) and Hg-S = 2.366(4) Angstrom, C-Hg-S = 177.0(5)degrees in molecule B]. The intramolecular (H-3)C-Hg-S---O(N0) fragment is near linear in each of the two independent molecules. (C) 1997 Elsevier Science Ltd. [References: 30]
