Abstract
7-Phenyl-3-(triphenylphosphinimino)- 1,3,5,-
2,4,6,8-trithiatetrazocine, C25H20N5PS3, Mr = 517.64,
monoclinic, P21/c, a = 13.957 (3), b = 9.242 (3), c
= 19.473 (4)/k, fl= 102.80 (2) °, V= 2449.4 A 3, Z
=4, Dx=l.4Ogcm -3, 2(MoKc0=0.71069A, ~=
3.8cm -1, F(000)=1072, T=293(1) K, final R=
0.038 for 2430 observed reflections. The molecule has a phenyl ring substituted at a planar carbon, and a
PhaP=N group substituted at S in the 3-position. The
CN4S3 ring is folded by 114.5 °, with an almost planar
SNCNS fragment, and an endo-S-envelope SNSNS
fragment (dihedral 145.0°). The PhaP=N substituent at
S is endo and the transannular S...S contact is
2.415 (1)A.
