THE X-RAY CRYSTAL STRUCTURE OF (DIPHENYLMONOTHIOPHOSPHINATO)TRIPHENYLTIN(IV), [PH3SN(OSPPH2)](N), EXHIBITING A POLYMERIC CHAIN SUPRAMOLECULAR SELF-ASSEMBLY

摘要

The molecular structure of (diphenylmonothiophosphinato)triphenyltin(IV) was determined by X-ray diffractometry. The diphenylmonothiophosphinato ligand is bimetallic biconnective leading to a polymeric [SnSPO](n) chain: Sn(1)--S(1) [2.785(3) Angstrom] and Sn(1)--O(1') [2.172(6) Angstrom]. The coordination geometry about tin is trigonal bipyramidal with chalcogen atoms in apical positions [O(1')--Sn(1)--S(1) 176.6(2)degrees] and carbon atoms of the phenyl groups attached to the metal in equatorial positions. The bridging pattern of the ambident monothio ligand is discussed in terms of partial bond orders and compared with those observed in other related organotin(IV) derivatives.
