Abstract:
Two new cantilever-type polyoxometalates Na(5)(NH(4)){V(IV)[(Mo(2)O(6))CH(3)C(O)(PO(3))(2)](2)}.13H(2)O (1) and (NH(4))(4){V(IV)[(Mo(2)O(6))NH(3)CH(2)CH(2)CH(2)C(O)(PO(3))(2)](2)}.6H(2)O (2) have been synthesized and characterized by IR spectroscopy, UV-visible spectroscopy, elemental analysis, TG analysis, XPS, (31)P NMR and single-crystal X-ray diffraction. The structure analysis reveals that the diphosphonate, hydroxyethylidene diphosphonic acid and alendronic acid as the scaffolds, have been grafted on the "S"-shaped polyoxoanions and respectively. The alkyl groups of the diphosphonates like arms hanged on the polyoxoanions form the cantilever-type polyoxometalates.

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...

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...
