Abstract
The title compound, [Sn(C4H9)2(NCS)2], which crystallizes with one and a half mol-ecules in the asymmetric unit, represents a new structure type for inter-molecular sulfur⋯tin inter-actions, which is characterized by an anti-parallel (A) arrangement of the dipole moments of the individual mol-ecules. In the resulting zigzag chains, the mol-ecules are related to each other by mirror planes (m) and twofold rotation axes (2), both perpendicular to the propagation plane, while translation is realized via a glide plane in direction of the crystallographic c axis, a combination of symmetry elements unique in the structural chemistry of diorganotin(IV) dihalides and pseudohalides, R2SnX2 with X = Hal or NCS. Its characteristics are subsumed in the term Am2c for this kind of inter-molecular association pattern. The tilting of the NSnN-planes in relation to the propagation plane is described in terms of spherical coordinates.
