Abstract:
The first study of fluxional motion in [Cu2(2-HPB)(MeCN)2Cl2] (1,2-HPB = hexa(2-pyridyl)benzene) is presented. For detailed examination of the fluxional motion mechanism, a monofluorinated derivative of the ligand (MFHPB) and its copper(i) complexes were synthesized and characterized. The solution NMR studies of monofluoro copper(i) complex 1a suggest the existence of five species in equilibrium. NMR spectra and DFT calculations suggest the fluxional motion of 1 resulting in the "metal hopping process" of two copper(i) ions.

Metal-Ligand Bonds
In these complexes, transition metals form coordinate covalent bonds, a kind of Lewis acid-base interaction in which both of the electrons in the bond are contributed by a donor (Lewis base) to an electron acceptor (Lewis acid). The Lewis acid in...

Crystal Field Theory - Octahedral Complexes
To explain the observed behavior of transition metal complexes (such as colors), a model involving electrostatic interactions between the electrons from the ligands and the electrons in the unhybridized d orbitals of the central metal atom has been developed. This electrostatic model is crystal field theory (CFT). It helps to understand, interpret, and predict the colors, magnetic behavior, and some structures of coordination compounds of transition metals.
CFT focuses on...
