Supramolecular organotin tris-carboxylates: crystal and molecular structure of [Cy2NH2]2[1-Me3(H2O)SnOCO-3,5-(OOC)2C6H3]·EtOH

The crystal and molecular structure of [Cy2NH2]2[C6H3(CO2)3SnMe3·H2O]·CH3CH2OH (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 O2SnC3 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
