| Popis: | The crystal and molecular structures of Ph 3 SnCHClCH 2 SC 6 H 3 NO 2 -2-Y-4 (II, Y Me) and Ph 3 SnCH(SCN)CH 2 SC 6 H 4 NO 2 - o (III) have been determined. Compounds II and Ill are adducts of Ph 3 SnCHCH 2 and the appropriate sulphenyl chloride and thiocyanate. Both compounds are monomeric and contain slightly distorted tetrahedral tin atoms. The intra-molecular SnS(R) distances in II (Y Me) and III are 3.67 and 3.58 A, respectively. The solid state conformations are staggered and have dihedral angles SnCCS of 56.6 and 57.4° in II (Y Me) and III, respectively, and ClCCS in II and SCCS in III 176.0° and 174.1°, respectively. From 3 J (HH) and 3 J ( 119 Sn 1 H) values, the solid state conformation of II (Y Me) is calculated to be populated in solution for approximately 1/3rd of the time at 25°C. |
