N2 - Two mercury(II) complexes containing imidazolidine- 2-Thione (Imt) and thiocyanate or cyanide ligands, [Hg(Imt)2(SCN)2] (1) and [Hg(Imt)2(CN)2].Hg(CN)2 (2), have been prepared and characterized by IR and NMR spectroscopy and X-ray crystallography. In compound 1, the mercury atom is located on a two-fold rotation axis and is coordinated to two thione sulfur atoms of imidazolidine- 2-Thione (Imt) and to two sulfur atoms of thiocyanate in a distorted tetrahedral mode with the S-Hg-S bond angles in the range of 98.96(3)-148.65(6)°. In 2, the mercury atom is hexa-coordinated having a distorted octahedral geometry composed of two cyanide C atoms [Hg-C 2.055(5) Å] and four weakly bound thione S atoms of imidazolidine-2-Thione (Imt) [Hg-S 3.1301(13) and 3.1280(13) Å]. One free Hg(CN)2 molecule is also present in the crystal. In both complexes, the molecular structure is stabilized by N-H?N and N-H?S hydrogen bonding interactions.
