Supramolecular organotin tris-carboxylates: Crystal and molecular structure of [Cy 2NH 2] 2[1-Me 3(H 2O)SnOCO-3,5-(OOC) 2C 6H 3]·EtOH

The crystal and molecular structure of [Cy 2NH 2] 2[C 6H 3(CO 2) 3SnMe 3•H 2O]•CH 3CH 2OH (1) has been determined by single crystal X-ray diffraction analysis. In this compound, the tin atom is pentacoordinated by three methyl groups, one oxygen atom of a water molecule and one oxygen atom deriving from the tris-carboxylato ligand, in a trans-coordinated O 2SnC 3 environment. The dicyclohexylammonium cations are involved in intermolecular hydrogen bonds with the non-coordinated oxygen atoms of the carboxylate, while, along with hydrogen bonds involving water and ethanol, gives rise to a complex 3D lattice structure.
