Abstract:
In this study, we explore the coordination complexes of the resorcinol bis(diphenylphosphinite) (POCOP) pincer ligand with Group 13 (aluminum, gallium and indium) metal centers. We report the synthesis of six new Group 13 POCOP complexes that have all been structurally characterized. The aluminum and indium complexes all crystallize in a five-coordinate "closed" geometry; however, for gallium, an "open" four-coordinate complex is additionally observed in the solid state, similar to an intramolecular frustrated Lewis pair.

Structural Isomerism
Isomers are different chemical species that have the same chemical formula. Structural isomerism of coordination compounds can be divided into two subcategories, the linkage isomers and coordination-sphere isomers.
Linkage isomers occur when the coordination compound contains a ligand that can bind to the transition metal center through two different atoms. For example, the CN− ligand can bind through the carbon atom or through the nitrogen atom. Similarly, SCN− can...

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.
