Abstract The crystal structure of 2,2,6-trimethyl-1,3-dithia-6-aza-2-stannocane has been determined and refined to R = 0.043. The transannular 1,5-distance Sn ⋯ N = 256.6(6) pm exceeds the respective single bond by 49 pm. A comparison with analogous eight-membered rings exhibits a clear-cut correlation of such differences with angle deformations in the transition tetrahedron to trigonal-bipyramid. The axial distance SnC is 2 pm longer than the equatorial one.
