The structure of the tin-containing clathrochelates cyclohexadione-1,2-dioximate (NBu4)[CoNx3 (SnCl3)2] (A) and dimethylglioximate (NBu4)[CoDm3(SnBr3)2]·H2O (B) have been determined by X-ray methods. Crystal data: (A) is orthorhombic, space group P212121 a = 16.566(4), b = 16.551(4), c = 16.560(4)Å, Z = 4; (B) is orthorhombic, space group Pca21, a = 16.271(3), b = 15.337(3), c = 18.572(4)Å, Z = 4. The cobalt(III) atoms are encapsulated by the clathrochelate ligands and surrounded by a distorted octahedral coordination polyhedron.
