Abstract
The crystal structure of the ethanol solvate of the title compound, [Hg(phen)3](CF3S03)2 (phen =1,10-phenanthroline), has been determined at 295(1) K by single-crystal X-ray diffraction and refined by least squares to a residual of 0�043 for 2939 'observed' reflections. Crystals are monoclinic: C2/c, a 25�25(1), b 10�960(4), c 18�949(6) �, β 129�32(2)�, Z 4. The cation is centred on a crystallographictwofold axis and has approximate D3 point symmetry. The deviation of the mercury(II) environment from octahedral symmetry toward the trigonal-prismatic limit is considerable, the mean trans N-Hg-N angle being 154�52�. is 2�400 �. The unit cell volume is considerablydependent on crystallization solvent, being larger for the ethanol solvate than for solvent-free crystals obtained from aqueous solution.
