Eight organotin (IV) (mainly sulfato) adducts have been synthesized and studied by spectroscopic methods. While considering the anionic component, the suggested structures are discrete; supramolecular architectures are obtained with secondary interactions through NH----Cl and NH----O hydrogen bonds while considering the cations, the anions behaving as monochelating, bridging or monocoordinating ligands, the environment around the tin (IV) centre being octahedral. Tetrahedral SnMe2Cl2 has been characterized spectroscopically.
