title: [μ-1,2,3,4-Tetra-kis(pyridin-4-yl)butane-κ(2) N (1):N (4)]bis-[trimeth-yl(thio-cyanato-κN)tin(IV)].
abstract: In the title compound, [Sn2(CH3)6(NCS)2(C24H22N4)], the 1,2,3,4-tetra-kis-(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 mol-ecule shows a distorted trans-trigonal-bipyramidal coordination with the methyl groups in equatorial positions. The mol-ecule 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⋯π inter-actions occur between pyridine rings of adjacent mol-ecules.
