Abstract: 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 Sn^IV 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 interactions occur between pyridine rings of adjacent molecules.
