Oxy- and Thio- Phosphorus Acid Derivatives of Tin. III. The X-ray Crystal and Molecular Structure of Bis-(O-O' -- Diphenyldithiophosphato) tin (II), Sn(s2P(OC6H5)2)2, a Bicyclic Dimer Held Together by h6-C6H5 to Tin (II) Interactions.
Abstract
The structure was studied by Monochromated Mo-K sub alpha radiation and refined to a final R value of 2.9% for 5517 reflections. The centrosymmetric, dimer contains one liqand bridging two tin atoms intermolecularly while simultaneously chelating one tin atom in an extremely anisobidentate manner. A planar Sn2S2four-membered ring is circumscribed by an (SnSPS)2 eight-membered ring. The dimer is in addition held together by a long pi-interaction of 3.46A along and S-Sn vector to be the center of one of the aromatic rings of an ester group of the bridging ligand of the second monomeric unit. This ring is oriented in a spacially significant position perpendicular to the assumed vector of the tin lone pair producing a distorted octahedral (4-6) geometry at the metal center.
