Abstract:
Germa-closo-dodecaborate reacts with the elements sulfur, selenium and tellurium to give well defined products: [S-GeB(11)H(11)](2-), [Se-GeB(11)H(11)](2-) and [Te-GeB(11)H(11)](2-). The chalcogen adducts were characterized by single crystal structure analysis, NMR and IR spectroscopy. By using quantum chemical methods the nature of the germanium chalcogen bond was studied. Furthermore the first transition metal complexes of [S-GeB(11)H(11)](2-) and [S-SnB(11)H(11)](2-) with Pd and Pt were synthesized and characterized, showing that the dianionic chalcogen adducts can be used as new ligands in transition metal chemistry.

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...

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 be...
