Abstract
A series of new complexes of the cyoe trins Na[co(NC2)2 (AA)2](where RA = 3-dthetone, e.g. acstoacatanilide o-chloroacetoncetanilue, o-acstoacatanilide, o-acstoacat-o-toluioiae, m-acetoacatoxylioide and benzoylacetanll lde have been synthesized and charaeterized on the basts of elemental analysis, magnetic susceptibility measurements, infrared and electronic spectra. The complexes exhibit a band at around 20,000cm-1 due to tha 1A1g→1Tlg transition. The complexes are Gianaygnetic and octanedral. The trans-scrueture has been assignea to the complexes on the basis of tafrared data.
