Article abstract of DOI:10.1007/BF00746435

The structure of phenylmercury 2-dimethylaminothiophenolate has been determined by x-ray diffraction (R = 0.0277 from 3227 reflections).The mercury atom has the typical linear configuration of the valence bonds, which have their usual lengths, Hg-C 2.076(6) and Hg-S 2.365(2) Angstroem.At the same time, for the observed conformation of the molecule, the Hg atom approaches the N atom of the dimethylamino-group to a distance of 2.657(6) Angstroem, corresponding to a secondary bond.The nitrogen atom has a pyramidal bond configuration, and its unshared electron pair is oriented towards the mercury atom.The presence of the secondary bond Hg...N does not lead to significant bending of the S-Hg-N unit (the angle at the Hg atom is 178.0(2) deg).
