The synthesis in very mild conditions of three new nicotinic acid complexes of Cr(III) are reported. The D NMR study of the d2-nicotinic acid complexes reveals that nicotinic acid is bound to chromium(III) through the carboxylic group in all cases. The ternary complex with histidine shows zero field splitting in its EPR spectrum indicating a distorted octahedral geometry for this complex. © 1992.
