“…The phosphine chelates to tin in an unsymmetrical fashion to form octahedral complexes. The two different Sn-P bond lengths observed in the solid state corroborate well with the low temperature 31 P NMR spectra which exhibit two different J(Sn-P) values in all the organotin complexes. In solution these complexes undergo facile redistribution to form [SnCl 4 (cis-dppen)].…”

“…Only configuration I can give rise to two different phosphorus environments leading to an ABX type spectrum. The low temperature (200 K) 31 P NMR spectra are consistent with form I. The absence of tin satellites for the major peak at ambient temperature 31 P NMR spectra shows that some kind of exchange is occurring at this temperature.…”

“…The low temperature (200 K) 31 P NMR spectra are consistent with form I. The absence of tin satellites for the major peak at ambient temperature 31 P NMR spectra shows that some kind of exchange is occurring at this temperature. Ligand dissociation has been widely observed in the adducts of tin(IV) halides or organotin(IV) halides with phosphine ligands [24,27] and found to be the major cause for room temperature line broadening in the 31 P NMR spectra.…”

Organotin(IV) complexes of the type [RSnCl 3 (cis-Ph 2 PCH@CHPPh 2 )] [R = Me (1), n Bu (2), Ph (3)] were prepared by the reaction of RSnCl 3 with the rigid bisphosphine ligand, cis-1,2-bis(diphenylphosphino)ethylene in dichloromethane. The complexes have been characterized both in solution and the solid state. Low temperature 31 P and 119 Sn NMR studies indicate two different phosphorus environments. The crystal structures indicate a weak but chelating mode of coordination of the two phosphorus atoms to tin, leading to a distorted octahedral geometry. In solution the complexes 1-3 undergo a redistribution reaction to form [SnCl 4 (cis-Ph 2 PCH@CHPPh 2 )] (4) as one of the products. In order to confirm the redistribution, complex 4 has been prepared separately and characterized both structurally and spectrally.

“…Oximes, including internally functionallized oximes, constitute an important class of N/O type donor ligands [34][35][36][37][38][39] because of their varying coordination abilities with the metal centers. Our previous studies on oximato complexes with some main group and transition metals show quite interesting structural features in both the solution and solid states [40][41][42][43][44][45][46][47]. The distinctive preference of the vanadium ion for these types of ligands has further promoted the synthesis and characterization of many model complexes containing N/O donor ligands [2,3,6,12,25,33,48,49].…”

New heteroleptic oxovanadium(V) chloro oximato complexes of the type [VO{Cl} 3-n {ON=C(CH 3 )(Ar)} n ] (where Ar = C 4 H 3 O-2, C 4 H 3 S-2, C 5 H 4 N-2 and n = 1 or 2) have been synthesized in excellent yields by the reaction of VOCl 3 with the sodium salts of corresponding internally functionallized oximes in refluxing anhydrous benzene. The complexes are characterized by elemental analyses and spectroscopic techniques (FT-IR, 1 H-, 1 3C{ 1 H}-and 51 V-NMR). FAB mass spectral analysis of one of the derivatives, [VOCl{ON=C(CH 3 )C 4 H 3 S} 2 ] indicates the monomeric nature of the complex. 51 V-NMR spectral studies of these complexes suggest tetra-coordination around the vanadium atom in solution. However, the single crystal X-ray diffraction study of a redistribution product [VOCl{ON=C(CH 3 )(C 4 H 3 S-2)} 2 ] AE CH 3 OH obtained on recrystallization of [VOCl 2 {ON=C(CH 3 )(C 4 H 3 S-2)}] from a methanol-hexane mixture shows the vanadium(V) atom is hepta-coordinated with distorted pentagonal bipyramidal geometry. The oxo-atom occupies the axial position while the weakly coordinated CH 3 OH group is trans to the V=O atom. The two oximato ligands in the approximate pentagonal plane are bonded to the central vanadium atom in dihapto (g 2 -N, O) manner with the formation of three-membered rings. The V-Cl bond occupies the fifth position in the approximate plane.

“…All the products of 1-3 were characterized by elemental analyses, IR, TGA and single-crystal X-ray diffractions. In the IR spectra, the medium-intensity absorption appearing at 432-434 cm À1 , which is absent in the spectrum of the free ligand, is assigned to the Sn-O stretching vibration [8,9]. And the other medium-intensity band appearing at 668-669 cm À1 is assigned to the Sn-N stretching vibration.…”
