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.

Isotopic Shifts

2,3-Pyrazinedicarboxamide and its 2H and 15N isotopic derivatives were synthesized with an isotopic content of 99.4%. The molecular geometry has been optimized by the MONSTERGAUSS ab initio method. Infrared and Raman spectra were recorded and assigned on the basis of isotopic shifts. The proposed assignments are fully in accordance with the Cs symmetry that was predicted by means of the theoretical calculations.
