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�. <Hg-N> 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.
