Gas-phase molecular structure of NN′-bis(trimethylsilyl)sulphur di-imide, determined by electron diffraction

Abstract

The molecular geometry of Me₃SiNSNSiMe₃in the gas phase has been studied by electron diffraction. The molecule has C₂ symmetry with a distorted syn,syn conformation. Principal parameters are: r_a(SN) 153.6(3), r_a(Si–N) 173.8(3), and r_a(Si–C) 186.9(1) pm; NSN 129.5(16), SNSi 132.9(7), and SN twist (relative to syn,syn conformation) 42(1)°.
