In the title compound, [Sn2(CH3)6(NCS)2(C24H22N4)], the 1,2,3,4-tetrakis(pyridin-4-yl)butane ligand uses the pyridine N atoms at the ends of the butyl chain to coordinate to two trimethylthiocyanatotin(IV) units, forming a dinuclear structure. The SnIV atom in the molecule shows a distorted trans-trigonal-bipyramidal coordination with the methyl groups in equatorial positions. The molecule lies on a center of inversion, with the mid-point of the butyl chain coinciding with this symmetry element. In the crystal, weak C-H...[pi] interactions occur between pyridine rings of adjacent molecules.
