Stoichiometric Complex

A stoichiometric complex of formula (COOH)2•2H2O•18-crown-6 has been obtained from oxalic acid and the macrocyclic polyether 18-crown-6. The crystals of the complex have a monoclinic unit cell and belong to the P21/c space group. The components in the adduct are linked through hydrogen bonds in a polymer-like fashion: -crown–H2O–HOOCCOOH–OH2–crown–, where the oxalic acid molecules are present in two distinct disordered orientations. The infrared and Raman spectra of the complex are also reported and interpreted.

First Time

The Raman spectrum of gaseous TeCl2Br2 at 310 °C is reported for the first time. The gas phase data is consistent with the presence of a monomolecular species haying C1 symmetry. A synthetic route for the preparation of penta- and hexa-co-ordinate mixed halide anions of tellurium(IV), under anhydrous conditions, is described for the first time. The infrared and Raman spectra for solid [Et4N]TeCl2Br3 and [Et4N]2TeCl2Br4 are reported. A stereochemistry based on a square pyramid, is favored for [Et4N]-TeCl2Br3. In the case of [Et4N]2TeCl2Br4 the vibrational data strongly suggests the presence of a cis-octahedral anion, having C2v symmetry.
