Abstract
Two independent molecules comprise the asymmetric unit in the title compound, [Sn(C
4
H
9
)(C
14
H
19
N
4
S)Cl
2
]. In each molecule, the Sn
IV
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].
