ABSTRACT
Hg(MeSe)2 or C2H6Se2Hg, bis(methaneselenolato)mercury. To obtain this compound, an excess metallic Hg was stirred with Me2Se2 (15 mmol) in pyridine (50 mL) for 2 days (Arnold and Canty 1981). The resulting yellow and black suspension was extracted with hot pyridine until the extract was colorless (200 mL), the black HgSe and metallic Hg being removed by ltration through cellulose powder and a ne sinter under slight positive pressure. Yellow leaets of C2H6Se2Hg were formed on cooling. This compound crystallizes in the monoclinic structure with the lattice parameters a = 844.0 ± 0.4, b = 1073.2 ± 0.3, c = 668.1 ± 0.3 pm, and β = 96.14° ± 0.04° and calculated density 4.29 g · cm−3 (Arnold and Canty 1982). Its crystals were grown from pyridine.
