摘要：

Amido rotation in the chromium(m), d(0)-system NCr(NP2I)(2)X is under investigation as a method for the parameterization of ligands for their donor properties toward high valent metals. In this study, two new series were prepared and studied based on chalcogenide tigands, X = EBut and EPh and where E = 0, S. Se, Te; the OPh and SPh compounds were previously reported. The ligand donor parameters for these ligands correlate with the Cr-E-C angles in these chatcogenide series. In addition, it was found that NBO calculated overlaps and DFT calculated bond dissociation enthalpies correlate within X = halide-, EBut-and EPh-series. All of the new complexes were characterized by X-ray diffraction.
