Abstract:
Five new metal-metal bonded Ru2 compounds are presented and discussed: Ru2(ap)4ONO2 (2), [Ru2(ap)4NCMe][BF4] (3), Ru2(ap)4FBF3 (4), Ru2(ap)4OTf (5), and [Ru2(ap)4OTf][Ag(OTf)2] (6) (ap = 2-anilinopyridinate). All compounds have a (4,0) arrangement of the ap ligands about the Ru-Ru bond and contain one sterically blocked axial site and one site containing a labile ligand. These compounds display some of the shortest Ru-Ru distances known for this class of compounds. We demonstrate a reversible interconversion between compounds 3 and 4 as the MeCN and BF4- ligands are readily displaced. Despite the presence of labile axial ligands, compounds 2-5 remain high spin with an S = 3/2 ground state as determined by EPR spectroscopy.

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...
