Chromium aminocarbene complexes [(CO)5Cr C(N(CH3)2)R], R N-methyl-2-pyrrolyl, 2-thienyl and 2-furyl were prepared and structurally characterized. X-ray study indicated two stable rotamers in case of compounds containing 2-thienyl and 2-furyl substitu

Redox potentials of series of chromium aminocarbene complexes with general formulas [(CO)5Cr═C(R)N(CH3)2] and [(CO)4Cr═C(R)N(CH2CHCH2)2] were calculated using DFT methods for both metal-localized oxidation and ligand-localized reduction processes
