DOIAbstract
The heterobimetallic complexes [Mn(<sup><i>i</i></sup>PrNPPh<sub>2</sub>)<sub>3</sub>Cu(<sup><i>i</i></sup>PrNHPPh<sub>2</sub>)] (<b>1</b>) and [Fe(<sup><i>i</i></sup>PrNPPh<sub>2</sub>)<sub>3</sub>Cu(<sup><i>i</i></sup>PrNHPPh<sub>2</sub>)] (<b>2</b>) have been synthesized by the one pot reaction of LiN<sup><i>i</i></sup>PrPPh<sub>2</sub>, MCl<sub>2</sub> (M = Mn, Fe), and CuI in high yield. Addition of excess CuI into <b>2</b> or directly to the reaction mixture led to the formation of a heterotrimetallic [Fe(<sup><i>i</i></sup>PrNPPh<sub>2</sub>)<sub>3</sub>Cu<sub>2</sub>(<sup><i>i</i></sup>PrNPPh<sub>2</sub>)] (<b>3</b>) in good yield. Complexes <b>1</b>–<b>3</b> have been characterized by means of elemental analysis, paramagnetic ...
