| Popis: | Nickel(II) complexes of 3-substituted-2, 4-pentanediones (R-acacH,R = Cl, Ph, NO2) and their adducts with 2,2′-bipyridine (bipy) and 1,10-phenanthroline (phen) have been synthesised and characterised by microanalyses, conductance, magnetic and spectral measurements. Four different nickel(II) complexes of 3-phenyl-2, 4-pentanedione have been isolated. The conductance data show that they are non-electrolytes except for the [Ni(phen)3I (Ph-acac)2, [Ni(phen)3] (Cl-acac)2 and [Ni(phen)3] (NO2-acac)2 adducts which are 1:2 electrolytes in nitromethane. The ligand field spectral bands of [Ni(NO2-acac)2]·2H2O suggest that this compound is a mixture of octahedral and tetrahedral species in solution. The infrared spectral shifts in the adducts suggest the formation of Ni-N bonds while the presence of carbonyls in different environments was observed in [Ni (NO2-acac)2 · phen2], [Ni (phen)3] (Cl-acac)2, [Ni(phen)3I (Ph-acac)2 and [Ni(phen)3] (NO2-acac)2. Octahedral coordination about the nickel (II) ion and t... |
