Abstract
Mercury 8-selenolquinolinate was synthesized and studied by X-ray diffraction. In neutral Hg(C9H6NSe)2, 8-selenolquinoline is a bidentate (S,N) ligand. The coordination polyhedron of mercury is a distorted tetrahedron or a seesaw (2Se + 2N). The bond lengths are as follows: Hg-Se, 2.4599(9) and 2.4606(9) Å; Hg...N, 2.497(6) and 2.513(6) Å. The SeHgSe bond angle is 166.07(3)°. Mercury 8-selenolquinolinate belongs to the class of chelates in which the five-membered chelate rings-Hg-Se-C-C-N-contain a donor selenium atom. The structures and the Hg-Se, Hg-S, Hg-O, and Hg-N bonds in mercury 8-selenol-, 8-mercapto-, and 8-hydroxyquinolinates were analyzed.
