Interelectronic repulsion is considered for pseudo-octahedral d6 and d7 complexes in the glassy state when there is ambiguity in the order in which the d-orbitals are populated. Ligand (R)eld stabilization energies are calculated for simple octahedral geometries, as well as 5-coordinate complexes...
Tetragonal ligand fields in copper(II) (square pyramidal or elongated octahedral) split the d-orbitals such that there is a dx2−y2 ground state (unpaired electron in the dx2−y2 orbital). In the AOM (angular overlap model) formalism [16] this is at an energy of 3eσ (in-plane don...
The synthesis, characterization and evaluation in solid-state devices of a series of 8 cationic iridium complexes bearing different numbers of methoxy groups on the cyclometallating ligands are reported. The optoelectronic characterization showed a drama
As with the Ru(II) and Ir(III) complexes, and in contrast to the Pd(II) and Pt(II) examples discussed below, the Ni(II) complex is observed to adopt an octahedral geometry in the single crystal, rather than square planar (Fig. 21) [59]. This is in line with many other ...
Photoredox nickel catalysis has emerged as a powerful strategy for cross-coupling reactions. Although the involvement of paramagnetic Ni(I)/Ni(III) species as active intermediates in the catalytic cycle has been proposed, a thorough spectroscopic investi
