A 4-coordinate Ru(ii) imido: unusual geometry, synthesis, and reactivity†
Abstract
A 4-coordinate Ru(II) imido complex, Ru(NAr)(PMe3)3 (1), can be prepared from cis-RuCl2(PMe3)4 and LiNHAr. The structure of the imido is perhaps best described as a flat-based trigonal pyramid with the imido in the equatorial plane. A possible explanation for the unusual geometry is discussed, along with some reactivity of 1.
