Title: Crystal structures of bis(cyanido)bis(N,N Prime -diethylthiourea-{kappa}S) mercury(II) and bis(cyanido)bis(N,N Prime -dipropylthiourea-{kappa}S) mercury(II)

Two mercury(II) complexes containing cyanide and, N,N Prime -diethylthiourea (detu) and N,N Prime -dipropylthiourea (dprtu) ligands, [(detu){sub 2}Hg(CN){sub 2}] (1) and [(dprtu){sub 2}Hg(CN){sub 2}] (2), respectively, have been prepared and characterized by X-ray crystallography. In the both complexes Hg atom lies on a 2-fold rotation axis, and is coordinated to the sulfur atoms of two thiourea ligands and to two cyanide carbon atoms. Both have a distorted tetrahedral environment with bond angles about the Hg atoms in the range of 93.41(4) Degree-Sign -146.75(19) Degree-Sign . In the crystal structures symmetry related molecules are linked via N-H-N hydrogen bonds resulting in the formation of a two-dimensional network in 1, while in 2 a double stranded one-dimensional chain is formed.
