catena-Poly[triethylammonium [[triphenyltin(IV)]-μ-3,3′-dihydroxy-4,4′-methylenedi-2-naphthoato]]

Abstract

The title compound, {(C6H16N)[Sn(C6H5)3(C23H14O6)]}n, has an infinite chain structure, formed through monodentate carboxylate groups of the pamoic acid anion. The anion bridges two symmetry-related Sn(IV) ions and the resulting polymeric chains are parallel to [201] in the crystal. Et3NH+ cations are inserted between the chains. The coordination of the Sn(IV) atom is completed by three phenyl ligands, giving a distorted trigonal–bipyramidal geometry.
