Final Agreement

The title compound has been prepared by the reaction of SbF5 and SbCl5 in liquid SO2. Raman and Mössbauer spectra have been recorded and its crystal structure determined by three-dimensional X-ray counter measurements. Crystals are monoclinic with a = 12.359(6) Å, b = 16.480(10) Å, c = 9.387(3) Å, β = 103.96(5)°. The structure has been refined in the space group P21/n to a final agreement index R2 of 0.113 for 2415 independent reflections. The structure consists of a cis fluorine-bridged trimer with one of the chlorine atoms 25% substituted by fluorine.

Abstract Polymeric bis(dimethyl-and diphenylglyoximato)-complexes of Fe(II) and Co(II) with pyrazine as a bridging ligand have been synthesized. The Co(II) complexes are para-magnetic with μ = 1.83 B.M., and surprisingly stable against oxidation. Bis (dimethyl-glyoximato)pyrazine-cobalt (II) crystallizes monoclinic in the space group C2/m with Z = 2. The crystal structure shows linear chains of alternating Co atoms and pyrazine ligands. Perpendicular to the chain, the Co atoms are coordinated in a square planar arrangement by two dimethylglyoximato ligands (Co-N= 189 pm), the local symmetry being C2h-The long Co-pyrazine distance of 224 pm is in agreement with the fact that the compound is a 19 electron complex. The Co complexes do not have conducting properties. The Fe(II) complexes possess the same structure but with stronger bonds in the chain. They show very low conductivity of approximately 10-10 cm -1 Ω-1 . The Mössbauer spectra of the Fe-complexes are reported.

Bonding Scheme

The 125Te Mössbauer spectra of a number of Te(II) and Te(IV) complexes with sulfur-containing ligands have been measured. The Te(II) compounds exhibit large quadrupole splittings of 12.4 to 15.2 mm s−1 and isomer shifts (125I/Cu) of + 0.33 to + 0.91 mm s−1. These data are interpreted as evidence for the incorporation of some 5s character in the bonding scheme for several of the compounds, consistent with the interpretation of X-ray crystal structure data. For the Te(IV) compounds 6, 7, and 8 coordinate molecules have been studied containing tellurium in distorted octahedral, pentagonal bipyramidal, and dodecahedral coordination.
