The present paper reports the results obtained in the synthesis and ch
aracterization of Cr(III) compounds of K[CrL(NCS)4] types, where L = p
-chlorophenylpyridazone (L1), p-bromphenylpyridazone (L2) and p-tolylp
yridazone (L3). The compounds are characterized by elemental chemical
analysis, measurements of electrical conductivity and electronic, IR a
nd X-ray spectra.
