Abstract

 DENSITY FUNCTIONAL THEORY (DFT) USING PBE, PBE1PBE, B3P86, B97-1 AND BHANDHLYP FUNCTIONALS AS WELL AS MP2 CALCULATIONS EMPLOYING THE TZVP BASIS SET WERE USED TO STUDY THE FORMATION OF FOUR HOST-GUEST COMPLEXES WITH FORMULA [H3L···X]2+ (X=F-, CL-, BR- AND I-) IN WHICH THE HALIDE ANION FORMS A TRIPODAL CO-ORDINATION PYRAMID WITH THE FULLY PROTONATED FORM OF 1,4,7-TRIAZACYCLONONANE ([9]ANEN3, L). STERIC, ELECTRONIC, AND SOLVENT EFFECTS [1-2] IN FORMATION OF THESE COMPLEXES WERE INVESTIGATED. THE RESULTS OF CALCULATIONS ON THE STRUCTURAL PARAMETERS OF [H3L···CL]2+ SHOWED THAT THE CALCULATED DATA WITH BHANDHLYP FUNCTIONAL HAVE THE BEST AGREEMENT WITH THE EXPERIMENTAL DATA [3] AND ALL FIVE DFT METHODS GIVE THE BETTER RESULT THAN MP2. THE RESULT OF CALCULATIONS ON THE INTERACTION AND THE FORMATION ENERGIES, IN AGREEMENT WITH NBO AND AIM DATA, SHOWS THE FOLLOWING TREND FOR THE FORMATION OF COMPLEXES IN THE GAS PHASE: [H3L···F]2+>[H3L···CL]2+>[H3L···BR]2+>[H3L···I]2+.
