The molecular structure of germyl monothioacetate in the gas phase, determined by electron diffraction

Abstract

The molecular structure of gaseous germyl monothioacetate has been determined by electron diffraction. The only isomer present has the germyl group bonded to sulphur; the non-bonded Ge ⋯ O distance is substantially less than the sum of van der Waals radii for germanium and oxygen. Principal bond lengths and angles (r_a) are: r(Ge–S) 223.3(4), r(C–S) 176.5(7), r(CO) 122.4(8), and r(C–C) 149.3(10) pm; GeSC 96.7(4), SCO 124.1(10), and CCO 116.4(13)°. The heavy-atom skeleton is almost planar, with the Ge–S and CO bonds arranged cis to one another.
