Abstract

The title compound was prepared by reacting mercury(II) cyanide and tetramethylthiourea (Tmtu) in the molar ratio of 1:1.75. It was characterized by IR and NMR (¹H and ¹³C) spectroscopy, and X-ray crystallography. The appearance of a band around 2,200 cm^-1 in IR and a resonance around 145 ppm in ¹³C NMR indicated the binding of cyanide to mercury(II). The crystal structure of the title complex, [{(tetramethylthiourea)₂Hg(CN)₂}₂•Hg(CN) ₂] (1) consists of two independent [(Tmtu)₂Hg(CN) ₂] moieties bridged by a Hg(CN)₂ unit. The mercury atom in [(Tmtu)₂Hg(CN)₂] unit is coordinated to two thione sulfur atoms of Tmtu and to two cyanide carbon atoms in a distorted tetrahedral mode.
