Crystal structure of chlorobis(thiourea)mercury(II) chloride
MetadataShow full item record
The crystal structure of the title compound, has been determined by single-crystal X-ray diffraction by conventional heavy-atom methods, and refined by block-diagonal least-squares to R 0簸 for 359 visually estimated reflections. Crystals are orthorhombic, space group Pmmn, a= 6紴 ᠰ簱, b= 12緶 ᠰ簲, c= 5繱 ᠰ簱 Ż Z= 2.The mercury atom is co-ordinated in an unusual approximately trigonal planar conformation by the two equivalent thiourea sulphur atoms and a chlorine atom (Hg-S 2紲 ᠰ簱, Hg-Cl 2絷 ᠰ簱 Ż S-Hg-Cl 110縠ᠰ粬 S-Hg-S 138素ᠰ粰). The other ionic chlorine atom lies normal to this plane, between and equidistant from a pair of mercury atoms at 3粲 Ů The thiourea molecules and the mercury and co-ordinated chlorine atoms are coplanar (Hg-S-C 110簠ᠰ繰); their intramolecular geometry is as expected.
