High resolution rotational spectra for 21 isotopic species of the hydrogen cyanide–mercury complex have been measured in the 7–15 GHz region using a Balle/Flygare pulsed Fourier transform microwave spectrometer. Rotational constants and 14N nuclear quadrupole coupling constants are (in MHz), for HC14N202Hg: B0=1265.6627(7), DJ=0.020 669(14), χN=−0.695(12), and for DC14N202Hg: B0=1201.8338(16), DJ=0.021 213(45), and χN=−0.748(19). The 201Hg nuclear quadrupole coupling constants are, for HC15N201Hg: −5.97(13) MHz, and for DC15N201Hg: −6.03(24) MHz. The atomic arrangement is HCN...Hg with a zero-point vibrationally averaged center-of-mass separation of 4.05 A(ring) for the most abundant HC14N202Hg species. The equilibrium structure was not determined. HCNHg does not exhibit the extreme centrifugal distortion and isotopic sensitivity effects seen in ArHCN [K. R. Leopold, G. T. Fraser, F. J. Lin, D. D. Nelson, Jr., and W. Klemperer, J. Chem. Phys. 81, 4922 (1984)].
