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 (
1
H and
13
C) spectroscopy, and X-ray crystallography. The appearance of a band around 2,200 cm
−1
in IR and a resonance around 145 ppm in
13
C NMR indicated the binding of cyanide to mercury(II). The crystal structure of the title complex, [{(tetramethylthiourea)
2
Hg(CN)
2
}
2
·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.
