### Abstract

Vibrational spectra with assignments and results of normal coordinate calculations for cyanomercuriomethanes CH_{4-n}(HgCN)_{n} (2 ≤ n ≤ 4) are discussed. The valence force constants of the central CHg bonds are 2.149, 1.944, and 1.798 N cm^{-1},while those of the HgCN bonds are 2.204, 2.123, and 2.162 N cm^{-1}, for n = 2, 3 and 4, respectively. All these force constants are lower than the corresponding constants for methylmercury cyanide (2.445 and 2.379 N cm^{-1}). The overall behaviour of these force constants as a function of the degree of mercuration n is quite similar in both the cyanomercuriomethanes CH_{4-n}(HgCN) and methylmercuriomethanes CH_{4-n}(HgCH_{3})_{n} series with the difference that there are variations in the constants at higher values in the former series. The potential energy distributions indicate that the valence vibrations of the CH, CN, and HgCN bonds are almost independent of all other vibrations, which in turn are more or less strongly coupled.

All these force constants are lower than the corresponding constants for methylmercury cyanide (2.445 and 2.379 N cm-1). The overall behaviour of these force constants as a function of the degree of mercuration n is quite similar in both the cyanomercuriomethanes CH4-n(HgCN) and methylmercuriomethanes CH4-n(HgCH3)n series with the difference that there are variations in the constants at higher values in the former series. The potential energy distributions indicate that the valence vibrations of the CH, CN, and HgCN bonds are almost independent of all other vibrations, which in turn are more or less strongly coupled.
