Abstract

The ladder-like structure of the tetranuclear title compound, [Sn4(C6H5)4Cl2O2(OH)2(C9H13N)2(C9H12N)2]Cl2·10CDCl3, consists of two five- and two six-coordinated SnIV atoms bridged by oxide or hydroxide groups. The chelating ligands reveal rather strong Sn—N bonds [2.517 (4) Å], but the protonated dimethylamino groups in the periphery of the complex show no interaction with the metal atoms. The complex cation is located on an inversion centre. The chloride anion is linked to the complex molecule by strong intramolecular O—H⋯Cl and N—H⋯Cl hydrogen bonds. Five independent deuterochloroform accompany the complex, two of them are disordered [occupancy ratios 0.63 (2):0.27 (2) and 0.60 (2):0.40 (2)].
