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 ener
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

Subsequent chapters look at the molecular orbital theory of transition metal complexes using a pictorial approach. Bonding in octahedral complexes is explored and electronic spectra and magnetic properties are given extensive coverage. The material addressed in this book forms the foundation of ...
Group 14 M(IV) complexes are illustrated by [SnF4(PCy3)2],988 trans-[SnCl4(PMe3)2],989 trans-[SnCl3(PMe3)2]+,989 and [SnCl2(PMe3)2]2+ (which has close Sn ⋯ Cl contacts with [AlCl4]− counterions),989 as well as octahedral [SnCl3(O3SCF3)(PMe3)2] with trans-PMe3...
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
852 As expected, the metal ion coordination number increases down group 2, and an example of CN = 7 is found in [Sr(pmedta){HC(CO2Me)2}2].853 Group 13 metal complexes with dien and pmdeta include the trigonal bipyramidal [AlH2(pmedta)]+,854 and octahedral fac-[M(dien)2]3+ (M...

When coordinated to first row transition metal atoms in octahedral complexes, the average N–M–N bond angle within the chelate ring is 84.7° (value obtained from 747 independent rings of 364 compounds). In the analogous NH3 complexes, the average cis N–M–N bond angle is 90.0° (value ...
