Reaction Conditions

Reactions of tetrakis(acetoxymercuri)methanes C(HgOOCCR3)4 (R = H, or F) in aqueous solutions with methylsulfane CH3SH, or sulfane H2S, yield tetrakis(methylthiomercuri)methane C(HgSCH3)4, and μ-dithiotetramercurimethane CHg4S2, respectively, both insoluble in common solvents and thermally remarkably stable. The central CHg4 groups of the starting materials have been preserved under the reaction conditions, thus tetrahedral entities C(HgS–)4 are common to both compounds. In the polymeric, amorphous CHg4S2 the CHg4 units are linked by sulfur bridges in a highly disordered manner, as is suggested by vibrational spectra. In other respects close similarities in the vibrational behaviour of these CHg4 fragments and of the isosteric NHg4 tetrahedra in tetramercurioammonium complexes have been observed.

Abstract By mixing aqueous solutions of Hg(CH3COO)2 and MOCN (M = K, Rb, Cs) the tri-clinic compounds M2Hg3(NCO)8 are formed. In a first approximation the crystal structure analysis indicates isolated Hg(NCO)2 molecules besides K+ and NCO- ions. As in the range of van der Waals radii additional NCO-neighbours are noticed the mercury atoms are surrounded by distorted octahedra. The octahedra around 2/3 of the Hg form infinite chains as in KHg(NCO)3 which are linked together by additional Hg(NCO)2 molecules. Therefore the compound can be formulated as a double salt 2 KHg(NCO)3 • Hg(NCO)2. The vibrational spectrum is discussed. Rb2Hg3(NCO)8 is isotypous while the caesium salt has a double cell volume.
