aminocarboxylic acids, such as 2-aminobenzoic acid, react easily with [ir(cod)(pme3)3]cl, (cod=1,5-cyclooctadiene), in thf to produce hydridoaminocarboxylato iridium(iii) complexes in high yields. these octahedral complexes are formed via oxidative addition reaction of the o-h bond of the carboxylic group with the central metal. the starting iridium(i) complex losses the cod molecule, the chlor...

In the context of low-energy Supersymmetry (SUSY), a model of Grand Unification (GUT) with right-handed (RH) neutrinos, based on the group SU(5), is discussed and its implications for neutralino dark matter (DM) are studied and compared with the constrained MSSM. RG effects in this model modify the sparticle spectrum such that the WMAP limit on the DM relic density cannot be satisfied for small...

glipizide has been found to form inclusion complexes with β-cyclodextrin (β-cd) in solution and in solid state. the present study was undertaken to determine a suitable method for scaling up glipizide-β-cd inclusion complex formation and to evaluate the effect of some parameters on the efficiency of complexation. the solid inclusion complexes of glipizide and β-cd were prepared at a molar ratio...

The solid state structures of two metal complexes of a hexaamine macrobicyclic ligand, in which the metal ion has an exact trigonal prismatic geometry, have been determined. Theoretical calculations showed this is the most stable geometry for d(0), d(10) and high spin d(5) metal complexes of the ligand with M-N bond distances >∼2.35 Å.
