“…The QS value ( = 2.95 mm/s) of this dinuclear compound is consistent with a dissymmetrical trans O 2 SnC 3 stereochemistry about the tin center according to Bancroft and Platt (1972). This allows suggestion of a monomeric structure, the environment around the tin center being dissymmetrical trans trigonal bipyramidal, and the anion PhPO 3 2-bi-unidentate: …”

“…The presence of ν s SnC 3 on the infrared spectra of ( 2 ) as a weak band is an indication of D 3 h symmetry for the SnC 3 residue. The value of the quadrupole splitting (QS) of ( 3 ) (QS = 3.57 mm/s) is consistent with the presence of a trans coordinated SnPh 3 group according to Bancroft and Platt (1972).

Four new phenylphosphonato SnR 3 (R = Ph, Me) derivatives have been synthesized and characterized by infrared and M ö ssbauer spectroscopy. The structure of catena-poly[PhPO 3 HSnMe 3 ] n has been determined by single-crystal X-ray diffraction analysis. The Sn IV atoms are five-coordinated in all compounds, with the SnC 3 O 2 framework in a trans trigonal bipyramidal arrangement and the PhPO 3 H -anions being in axial positions. The molecular structure of [PhPO 3 HSnMe 3 ] n is arranged as a one-dimensional coordination polymer in which planar SnMe 3 groups are axially bridged by -O-P-O-linkages of the PhPO 3 H -ligand. Neighboring chains are linked via O-H … O hydrogen bond interactions, generating a layered structure.In the R 2 NH 2 (PhPO 3 H) 2 SnR′ 3 (R = Cy, Bu; R′ = Ph, Me), the SnPh 3 or SnMe 3 residue is axially coordinated by two monodentate PhPO 3 H -. The role of the dialkylammonium cation, R 2 NH 2 + , is crucial in the lattice building via a hydrogen bond network. These hydrogen bonds contribute to the crystal stability and compactness and result in a three-dimensional arrangement. The aqua complex PhPO 3 (SnPh 3 ) 2 . 2H 2 O has a discrete structure and the anion PhPO 3 2-behaves as a bidentate ligand.

“…The M ö ssbauer spectrum of compound 2 shows a slightly asymmetric quadrupole split doublet with an isomer shift value (1.20 mm -1 ) in the In the IR spectrum, the bands located at 1060 (s, ν 1 NO 3 ), 1334, and 1375 (vs, ν 3 NO 3 ) cm -1 are assigned to the stretching vibrations of the NO 3 groups. The value of the quadrupole splitting of ( 3 ) (QS = 3.57 mm/s) is consistent with the presence of a trans hexacoordinated SnPh 2 group according to Bancroft and Platt (1972). The suggested structure for ( 3 ) consists of a trans-octahedral geometry around the Sn IV atom ( Scheme 2 ).…”

Four new di-and triorganonitrato stannate complexes and related derivatives have been synthesized and characterized by infrared and M ö ssbauer spectroscopy. The structure of Et 4 N[NO 3 (SnClPh 3 ) 2 (SnPh 3 NO 3 )] ( 1 ) has been determined by single-crystal X-ray diffraction analysis. In the trinuclear organostannate complex, each Sn IV atom is five-coordinated and adopts a trigonal-bipyramidal trans -OXSnC 3 (X = O or Cl) geometry. The overall coordination environment of the Sn IV atoms is trans-octahedral for 2 and 3 or cis-trigonal-bipyramidal for 4 . In the related derivatives, the NO 3 -anions behave as monodentate ligands.
