Two independent molecules comprise the asymmetric unit in the title compound, [Sn(C4H9)(C14H19N4S)Cl2]. In each molecule, the SnIV atom exists within a distorted octahedral geometry defined by the N,N′,S-tridentate mono-deprotonated Schiff base ligand, two mutually trans Cl atoms, and the α-C atom of the n-butyl 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 [151.72 (7) and 152.04 (7)°, respectively]. In the crystal, molecules are consolidated into a three-dimensional architecture by a combination of N—H...Cl, C—H...π and π–π interactions [inter-centroid distances = 3.6718 (19) and 3.675 (2) Å].
