ChemInform Abstract: Synthesis and Fluxional Behavior of Octahedral Manganese(I) Complexes with a Monodentate 1,8‐Naphthyridine Ligand. X‐Ray Crystal Structure of fac‐(Mn(η1‐1,8‐naph)(η2‐phen)(CO)3)ClO4·1/2 CH2Cl2 (naph: 1,8‐Naphthyridine, phen: o‐Phenanthroline).

Abstract

ChemInform Abstract The octahedral fac-complexes (III) with monodentately coordinated 1,8-naphthyridine (II) are obtained according to the scheme. Their structure is established by X-ray analysis of the o-phenanthroline complex (IIIa) (space group P21/a, Z=4). A detailed variable-temp. 1H NMR study show that at higher temp. these complexes are fluxional species in which a rapid metal exchange between the two N atoms of naphthyridine takes place.
