The redetermination of the crystal structure of trisulphur dinitrogen dioxide

Abstract

The crystal structure of S 3 N 2 O 2 has been redetermined and the structure refined to a final R of 0.057 and R w of 0.076 for 550 reflections with I ≥ 2σ(I). S 3 N 2 O 2 is planar and of C 2v symmetry, as previously found by Weiss. The central S—N distances and angle are 1.647(3) Å, NŜN 97.3(2)°, with adjacent N—S distances and angles of 1.535(3) Å, [Formula: see text], and terminal S—O distances and angles of 1.446(4) Å, NŜO 118.0(2)°. The infrared and Raman spectra are reported and some assignments are made.
