Coordination of Tri-Substituted Nona-Germanium Clusters to Cu(I) and Pd(0)
1Department of Chemistry and Biochemistry, University of Notre Dame, Notre Dame, Indiana 46556, United States.
Abstract:
The recently developed approach for the rational functionalization of deltahedral nona-germanium clusters Ge9(4-) with three substituents to form Ge9R3(-) (R = Si(SiMe3)3) in large amounts has made the latter a convenient starting material for further reactivity studies. Reported here are the synthesis, structures, and solution studies of two compounds where Ge9R3(-) are used as ligands to transition metals, [(Ge9R3)Cu(I)(Ge9R3)Cu(I)PPh3] (1) and [(Ge9R3)Pd(0)(Ge9R3)](2-) (2). The former adds to the families of anionic [(Ge9R3)M(I)(Ge9R3)](-) (M(I) = Cu, Ag, and Au) as a neutral member and of the neutral [(Ge9R3)M(II)(Ge9R3)] (M(II) = Zn, Cd, and Hg), while the latter represents the first compound involving a metal from group 10.

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.
CFT focuses on...
