摘要：

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