Abstract
Abstract Phenylmercury(II) acetate crystallizes in the monoclinic system, the space group P2 1 /c, with four molecules per unit cell. The unit cell dimensions are: a=5.24±0.01 A, b=24.20±0.04 A, c=7.50±0.02 A, β = 114.0±0.4°, the measured and calculated densities are 2.54 and 2.57 g/cm 3 , respectively. The structure has been solved using 551 independent reflections collected about c-axis on integrated equiinclination Weissenberg photographs and refined by least-squares method to R = 0.111. The structure is built up of the discrete C 6 H 5 HgOCOCH 3 molecules. The mercury atom is covalently bound to the phenyl ring in one side and to one acetate-oxygen atom on the other to give the characteristic digonal co-ordination. The HgC and HgO bond lengths are 1.92±0.06 and 2.11±0.04 A, respectively. The CHgO bond angle amounts to 170±2°.
