Abstract

An in-depth analysis of the description of bonding within Cp ''' Ni-cyclo-P-3 (Cp '''=1,2,4-tri-tert-butylcyclopentadienyl, [Ni]P-3) employing X-ray diffraction based multipolar modeling, density functional theory (DFT) as well as an "experimental wavefunction" obtained from X-ray restrained wavefunction (XRW) fitting is presented. The results are compared to DFT calculations on white phosphorus - an isolobal analogue to [Ni]P-3. A complementary bonding analysis shows insights into the reactivity of [Ni]P-3. The isolobal principle is reflected in every aspect of our analysis and the employed methods seamlessly predict the differences in reactivity of [Ni]P-3 and P-4. Crystallographic modeling, solid-state NMR, and DFT calculations describe the dynamic behavior of the cyclo-P-3 unit in the title molecule.
