title: Crystal structure of the 1:1 adduct of 2,3-diphenyl-3,4,5,6-tetra-hydro-2H-1,3-thia-zin-4-one with tri-phenyl-tin chloride.
abstract: The title adduct, chlorido-(2,3-diphenyl-3,4,5,6-tetra-hydro-2H-1,3-thia-zin-4-one-κO)tri-phenyl-tin, [Sn(C6H5)3Cl(C16H15NOS)], resulted from reaction of 2,3-diphenyl-3,4,5,6-tetra-hydro-2H-1,3-thia-zin-4-one with tri-phenyl-tin chloride. The thia-zine ring has an envelope conformation with the S atom forming the flap. The mol-ecule has five phenyl rings, two of them attached to the thia-zine ring at positions 2 and 3, and three in coordination with the Sn(IV) atom. The three rings of the tri-phenyl-tin group are involved in intra-molecular inter-actions of different types, C-H⋯O, edge-to-face (or T-type) π-π inter-actions with the 3-phenyl ring of the thia-zine, T-type inter-actions with both phenyl rings of the thia-zine etc. On the other hand, all the phenyl rings participate in inter-molecular π-π inter-actions. There is one instance of a 'parallel-displaced'-type inter-action extending continuously along the a-axis direction and seven instances of T-type inter-actions stabilizing the crystal lattice.
