Abstract

C2HIoN402P2S 2 is triclinic, Pi, with a = 6.396 (2), b = 7.987 (2), c = 9.652 (3)A, a = 89.23 (10), fl = 86.24(10), y = 87.92 (10) °, V= 491.7 (9)A3, z = 2, D c --1.676 Mg m -3. The structure was solved by direct methods and refined to R = 0.068 (R w = 0.048). The two symmetry-independent centrosymmetric molecules show a flattened chair conformation for the saturated six-membered rings [mean torsional angle of ring bonds 44.2 (1.9)°]. The S atoms are in equatorial, the methoxy groups in axial positions. Mean bond distances: N
