The Sn(IV) atom in the title compound, [Sn(C(6)H(5))(C(14)H(19)N(4)S)Cl(2)], exists within a distorted octa-hedral geometry defined by the N,N',S-tridentate monodeprotonated Schiff base ligand, two mutually trans Cl atoms, and the ipso-C atom of the Sn-bound phenyl group; the latter is trans to the azo-N atom. The greatest distortion from the ideal geometry is found in the nominally trans angle formed by the S and pyridyl-N atoms at Sn [151.03 (4)°]. With the exception of the cyclo-hexyl group (chair form), the Schiff base ligand is almost planar (r.m.s. deviation of non-H and Sn atoms = 0.053 Å). The nearly orthogonal orientation of the Sn-bound phenyl group [N-Sn-C-C torsion angle = 70.8 (5)°] to the planar portion of the Schiff base allows for the formation of significant intra-molecular C-H⋯Cl inter-actions which preclude the Cl atoms from participating in N-H⋯Cl hydrogen bonds. Instead, C-H⋯π contacts, involving methyl-ene H and the Sn-bound phenyl group, lead to the formation of supra-molecular chains that pack in the bc plane. Connections between these layers are of the type C-H⋯Cl.
