Novel mono- and heterobimetallic chromium-nickel s-indacene complexes: synthesis, characterization, and DFT studies

The preparation of a novel heterobimetallic chromium-nickel compound (3), including 2,6-diethyl-4,8-dimethyl-5-hydroindacenide (IcH') as bridging ligand was successfully achieved and it was characterized by means of ¹H NMR, ¹³C NMR, and FT-IR spectroscopies and elemental analysis. Cyclic voltammetry studies were performed for complex 3 as well as for its respective mononuclear species. Theoretical calculations of this compound were carried out to gain further understanding of this novel molecular system. (author)
