The crystal structure of phenylmercury(II) acetate

摘要: Abstract Phenylmercury(II) acetate crystallizes in the monoclinic system, space group P21/c, with four molecules per unit cell. The cell dimensions are: a=5.24±0.01 A, b=24.20±0.04 c=7.50±0.02 β = 114.0±0.4°, measured and calculated densities are 2.54 2.57 g/cm3, respectively. structure has been solved using 551 independent reflections collected about c-axis on integrated equiinclination Weissenberg photographs refined by least-squares method to R 0.111. is built up of discrete C6H5HgOCOCH3 molecules. mercury atom covalently bound phenyl ring one side acetate-oxygen other give characteristic digonal co-ordination. HgC HgO bond lengths 1.92±0.06 2.11±0.04 CHgO angle amounts 170±2°.
