An electron diffraction determination of the molecular structure of trifluoromethyl selenium cyanide

Abstract

The molecular structure of F 3CSeCN has been determined, in the vapour phase by the sector microphotometer method of electron diffraction. Two molecular conformations are consistent with the experimental data; for the physically more reasonable structure, the principal parameters are: C-F 1.332 ± 0.007, Se-C(F 3) 1.984± 0.020, Se-C(N) 1.854 ± 0.016, N-C 1.152±0.020 Å and angle C-Se-C, 92.2 ± 2.0°.
