| heal.abstract | Direct reaction of mercury(II) chloride with triphenylphosphine (PPh3) and benzothiazole-2-thione (bzthtH) in the molar ratio of 1:1:2 results in the formation of the [Hg(PPh3)(bzthztH)(bzthzt)Cl] (1) (bzthzt = the anion of benzothiazole-2-thione) while the reaction of mercury(II) chloride with triphenylphosphine (PPh3) and pyrimidine-2-thione (pmtH) in the molar ratio of 1:1:1 gives [Hg2Cl2(PPh3)(2)(pmt)(2)] (2) (pmt = the anion of pyrimidine-2-thione). The complexes have been characterised by their elemental analyses, melting points and their FTIR, far-IR spectroscopic data. The crystal structure of complex 1 which has: been determined by single-crystal X-ray crystallography at r.t. reveals that the molecule is monomeric with tetrahedral geometry around the metal ion. A benzothiazole-2-thione molecule and a benzothiazole-2-thionato anion are coordinated, via sulfur atoms, to the mercury(II) ion [Hg-S(ZA)= 2.726(2) and Hg-S(2)= 2.419(2) Angstrom]. A triphenylphosphine molecule is also coordinated through a phosphorus atom to the metal ion [Hg-P = 2.453(2) Angstrom] while the tetrahedral geometry around the mercury is completed by a chlorine atom [Hg-Cl= 2.633(2) Angstrom]. The complex is covalent in the solid state. The crystal structure of complex 2 which has also been established by single-crystal X-ray crystallography at 100(1) K shows that the molecule is binuclear and consists of two different moieties with tetrahedral geometry around each mercury(II) ion. One moiety consists of a mercury(II) ion with two phosphorus atoms from phosphine ligands and two bridging chlorine atoms, while the other consists of a mercury(II) ion and two sulfur atoms of pyrimidine-2-thionato ligands. The entire complex is covalent in the solid state. The two Hg(2)S(42) bond lengths are 2.3513(11) Angstrom while the two Hg(1)-P(1) bond lengths are 2.4826(9) Angstrom. The: two parts of the molecule are linked to each other by two chlorine atoms with Hg(1)Cl(1) and Hg(Z)-Cl(1) bond distances of 3.5310(10) and 3.0372(10) Angstrom, respectively.
