Square planar and tetrahedral chromium(II) complexes; crystal structure determinations
Abstract
The novel compound Cr[N(SiMe3)2]2(THF)2 has been prepared and characterised, and shown by X-ray crystal analysis to have the trans-square planar configuration; this contrasts with Cr(NO)[N(SiMe3)2]3 which has been found to possess a pseudo-tetrahedral (C3v) structure.
