Аннотация
Two mercury(II) cyanide complexes of N-ethylthiourea (Ettu) and N-propylthiourea (Prtu) ligands, [Hg(Ettu)2(CN)2] (1) and [Hg(Prtu)2(CN)2] (2), were prepared and their crystal structures were determined by X-ray crystallography. In both structures, the mercury atom is coordinated to two sulfur atoms of thioureas and two cyanide carbon atoms in a pseudo-tetrahedral mode with the bond angles in the range of 90.52(11)-162.2(3)°. The structures are stabilized by N-H---S, N-H---N, and C-H---N intramolecular and intermolecular hydrogen bonds.
