Abstract

Coordination compounds formed by the interaction of mercury(II) thiocyanate with some bidentate ligands—ethylenediamine, N,N-diethylethylenediamine, 1,3-propanediamine, 1,4-butanediamine, morpholine, methylpyrazine, 1,4-dioxane, 2,2´-bipyridyl, 1,10-phenanthroline, 2,2´-bipyridylamine, 2,2´-bipyridyl N,N´-dioxide, 4,4´-bipyridyl and 4,4´-bipyridyl N,N´-dioxide–have been prepared. Stoichiometries of the complexes have been established by metal and thiocyanate estimations gravimetrically. The complexes isolated in the solid state have been characterized by infrared spectral measurements down to 200 cm–1 to elucidate the mercury(II)-ligand and mercury(II)-thiocyanate bonding modes. Tentative stereochemistries of the complexes in the solid state are discussed.
