Synthesis of [Mo(η6-NC5H3Me2-2,6)(η6-C6H5Me)]: photoelectron spectra and electronic structure of some transition-metal η6-2,6-dimethylpyridine complexes
Abstract
Synthesis of the mixed-ring sandwich compound [Mo(η6-NC5H3Me2-2,6)(η6-C6H5Me)] is reported. Photoelectron spectroscopic studies of [M(η6-NC5H3Me2-2,6)2], where M = Ti, V, Cr or Mo and [Mo(η6-NC5H3Me2-2,6)(η6-C6H5Me)] established that these sandwich compounds are electronically very similar to the bis(arene) analogues, and that 2,6-dimethylpyridine is a better δ acceptor than benzene.
