An Electron Diffraction Investigation of Dimethyl Selenide

Abstract

The results of an electron diffraction investigation of (CH_3)_2Se arc C-H/Se-C, 1.09/1.97 ( assumed); Se-C, 1.977 ± 0.012 Å.; Se•••H, 2.571 ± 0.034 Å.; C•••C, 2.98 ± 0.23 Å.; ∠C-Se-C, 98 ± 10°; and ∠Se-C-H, 110.5 ± 3.5°. The selenium-carbon distance of 1.98 Å. leads to a single-bond radius for selenium of 1.22 Å., which is considerably larger than the value 1.17 A. chosen by Pauling.
