Crystal structure of the 1:1 adduct of 2,3-diphenyl-3,4,5,6-tetra­hydro-2H-1,3-thia­zin-4-one with tri­phenyl­tin chloride

The title adduct, chlorido­(2,3-diphenyl-3,4,5,6-tetra­hydro-2H-1,3-thia­zin-4-one-κO)tri­phenyl­tin, [Sn(C(6)H(5))(3)Cl(C(16)H(15)NOS)], resulted from reaction of 2,3-diphenyl-3,4,5,6-tetra­hydro-2H-1,3-thia­zin-4-one with tri­phenyl­tin chloride. The thia­zine ring has an envelope conformation with the S atom forming the flap. The mol­ecule has five phenyl rings, two of them attached to the thia­zine ring at positions 2 and 3, and three in coordination with the Sn(IV) atom. The three rings of the tri­phenyl­tin group are involved in intra­molecular inter­actions of different types, C—H⋯O, edge-to-face (or T-type) π–π inter­actions with the 3-phenyl ring of the thia­zine, T-type inter­actions with both phenyl rings of the thia­zine etc. On the other hand, all the phenyl rings participate in inter­molecular π–π inter­actions. There is one instance of a ‘parallel-displaced’-type inter­action extending continuously along the a-axis direction and seven instances of T-type inter­actions stabilizing the crystal lattice.
