D. Gurcay et al., An infrared and Raman spectroscopic study on the solvation of mercury(II) cyanide in aprotic donor solvents, J MOL STRUC, 483, 1999, pp. 65-68
Evidence based on the IR and Raman spectral features of HE(CN)(2) in twelve
solvents with widely different donor strengths supports the view that incr
easing solvent coordination to the Hg atom leads to a progressive reduction
of the C-Hg-C angle from 180 degrees. For solvents of high donor strength
(e.g. piperidine) the C-Hg-C interbond angle may approach 145 degrees. (C)
