A series of N-substituted carbazic acid complexes of chromium(
III) with a general composition CrL3 (where L = carbazic
acid anion, methylcarbazate, phenylcarbazate, 2,3-dimethylcarbazate
and 3,3-dimethylcarbazate) was prepared. On the basis of
infrared and electronic spectroscopy and magnetism, the structure
of these complexes was identified. The ligand field parameters
were calculated from the spectral data; the values of IODq for the
complexes studied are essentially constant, varying only from
17.09 to 18.34 kK*. The values of B in the complexes were reduced
very significantly from the free-ion value for chromium(III). The
bonding occurs through one of the oxygen atoms of the carboxylate
group and amino nitrogen atom.
