title: fac-(2-Amido-ethyl-κC,O)aqua-tri-chlorido-tin(IV) 1,4,7,10,13,16-hexa-oxacyclo-octa-decane (2/1).
abstract: The asymmetric unit of the title compound, [Sn(C(3)H(6)NO)Cl(3)(H(2)O)](2)·C(12)H(24)O(6), comprises a six-coordinate tin complex and a 18-crown-6 mol-ecule, the latter disposed about a centre of inversion. The tin atom is coordinated by three Cl atoms, that define a facial arrangement, a chelating C-,O- ligand, and a water mol-ecule. The resulting CCl(3)O(2) donor set defines a distorted octa-hedral geometry. The tin-bound aqua ligand forms O-H⋯O hydrogen bonds to the centrosymmetric 18-crown-6 mol-ecule, resulting in a tri-mol-ecular aggregate. These assemble into a supra-molecular chain along the a axis being connected by N-H⋯O hydrogen bonds.
