Ab initio calculations have been carried out on the molecules CH,NCX and CH,XCN (X=0, S and Se). It was found that these molecules all have a bent equilibrium structure. The relatively more rigid CH,XCN molecules can be sufficiently well described by small basis set Hartree-Fock calculations. The ac

✦ Synopsis
The equilibrium geometries of the germyl pseudohalides CieHJWX and GeH$CN (X=0, S and Se) have been obtained using 6-3 lG**/MP2 calculations. It was found that the -XCN derivatives of germane are strongly bent, whereas their -NCX isomers are quasilinear or linear. The calculated barrier to linearity of GeH,NCO is 48.3 cm-'. Harmonic vibrational frequencies for GeHsNCO and GeH&CN were also determined.
