  Metal-oxygen versus metal-sulfur bonding of the ambident monothiophosphinato ligand in some triphenylmeta(IV) derivatives, Ph3M[OSPR2] (M = Ge, Sn, Pb). Crystal structures of Ph3Ge[O(S)PPh2] and [Ph2Sn{O(S)PPh2} (μ-OH)]2

  摘要：

  Diorganomonothiophosphinato-triphenylmetal(IV) derivatives, Ph(3)M(OSPR(2)) (M = Ge, Sn, Pb; R = Me, Et, Ph), were prepared and investigated. The IR and multinuclear (H-1, C-13, P-31) NMR spectra are discussed in relation to the M-O and/or M-S bonding of the ambident OSPR(2)(-) ligand. The crystal and molecular structures of Ph(3)Ge[O(S)PPh(2)] (1) and [Ph(2)Sn{O(S)PPh(2)}(mu-OH)](2) (2) were determined by X-ray diffractometry. The asymmetric unit for Ph(3)Ge[O(S)PPh(2)] contains two independent molecules. The monothiophosphinato group is bonded to germanium only through oxygen (av. Ge-O 1.826, Ge ... S 3.892 Angstrom), leading to a tetrahedral coordination around the germanium atom. The crystal [Ph(2)Sn{O(S)PPh(2)}(mu-OH)](2) consists of dimeric units built up through Sn-O-Sn bridges involving the oxygen atom of the hydroxy groups. The monothiophosphinato group is again monodentate [Sn(1)-O(1) 2.089(3), Sn(1)... S(1) (non-bonding) 4.164 Angstrom] and the coordination geometry around tin is trigonal bipyramidal, with the O(1) atom of the phosphorous ligand and the O(2') atom of a bridging hydroxy group in axial positions.
