Synthesis and structural characterization of an air-stable 17-electron complex containing the {Cr(NO)}2+ core
Abstract
The reaction between [Cr(bdmpam)(CO)3][bdmpam = bis(3,5-dimethylpyrazol-1-ylmethyl)-aminomethane] and an excess of [NO][BF4] in MeCN gives the air-stable 17-electron monomeric product [Cr(bdmpam)(NO)(NCMe)2][BF4]2, which has been characterized by elemental analysis, i.r., e.s.r. spectroscopy, magnetic moment, and X-ray crystallography. The observed air stability of this paramagnetic monomer can be attributed to the presence of the bulky multidentate ligand bdmpam.
