【 摘 要 】

In the title complex, [Hg(NCS)2(CH4N2S)2], the HgII atom is four-coordinated having an irregular four-coordinate geometry composed of four thione S atoms of two thio­cyanate groups and two thio­urea groups. The S—Hg—S angles are 172.02 (9)° for the trans-thio­cyanate S atoms and 90.14 (5)° for the cis-thio­urea S atoms. The mol­ecular structure is stabilized by an intra­molecular N—H⋯S hydrogen bond, which forms an S(6) ring motif. In the crystal, mol­ecules are linked by a number of N—H⋯N and N—H⋯S hydrogen bonds, forming a three-dimensional framework. The first report of the crystal structure of this compound appeared in 1966 [Korczynski (1966). Rocz. Chem. 40, 547–569] with an extremely high R factor of 17.2%, and no mention of how the data were collected.
