    Notes: The reaction of 1-methyl-1,3-imidazole-2-thione (meimtH) with mercury(II) iodide in methanol in a 2:1 molar ratio resulted in the formation of single crystals of the title compound, [HgI2(C4H6N2S)2]. The Hg atom is coordinated by two I [2.7809 (9) and 2.7999 (8) Å] and two thione S atoms [2.520 (3) and 2.576 (3) Å] with irregular tetrahedral coordination geometry. The NH groups of the imidazole ring take part in intra- and intermolecular hydrogen bonds with I atoms [N...I 3.596 (8) and 3.611 (9) Å, respectively] joining molecules into infinite chains parallel to the z axis.

    Notes: The reaction of 3,4,5,6-tetrahydropyrimidine-2-thione (H4pymtH) with mercury(II) iodide in methanol in a 1:1 molar ratio resulted in the formation of single crystals of the title compound, [Hg(C4H8N2S)I2]. The Hg atom is coordinated by one S atom from H4pymtH at 2.456 (2) Å and by two I atoms at distances of 2.6872 (7) and 2.7044 (6) Å, and has a characteristic deformed trigonal coordination geometry. The molecule has crystallographic m symmetry but the Hg atom is disordered above and below the mirror plane.

    A 1:2 complex of mercury(II) chloride with 1,3-imidazole-2-thione (2000)

    Notes: The Hg atom in the title monomeric complex, dichlorobis(3-imidazolium-2-thiolato-S)mercury(II), [HgCl2(C3H4N2S)2], is four-coordinate having an irregular tetrahedral geometry composed of two Cl atoms [Hg—Cl 2.622 (2) and 2.663 (2) Å] and two thione S atoms [Hg—S 2.445 (2) and 2.462 (2) Å]. The monodentate thione ligand adopts a zwitterionic form and exists as the 3-imidazolium-2-thiolate ion. The bond angle S1—Hg—S2 of 130.87 (8)° has the greatest deviation from ideal tetrahedral geometry. Intermolecular hydrogen bonds between two of the four N—H groups and one of the Cl atoms [3.232 (8) and 3.238 (7) Å] stabilize the crystal structure, while the other two N—H groups contribute through the formation of N—H...Cl intramolecular hydrogen bonds with the other Cl atom [3.121 (7) and 3.188 (7) Å].

    Notes: The reaction of 2-methyl-1,3-benzothiazole (mebta) with mercury(II) chloride in methanol in a 1:1 molar ratio resulted in the formation of single crystals of the title compound, [HgCl2(C8H7NS)]n. The molecules exist as continuous chlorine-bridged chains in which Hg atoms lie in distorted trigonal bipyramidal environments. The equatorial positions are occupied by an N atom from the ligand [2.236 (8) Å] and two Cl atoms [2.428 (3) and 2.459 (3) Å]. The two axial Hg—Cl contacts to two neighbouring molecules [2.874 (3) and 2.964 (3) Å] are significantly shorter than the sum of the respective van der Waals radii, and form close to linear Cl—Hg—Cl sequences [177.80 (7)°].
