Abstract:
The hydrothermal reactions of α-K(4)SiW(12)O(40) with NiCl(2)·6H(2)O yielded two unprecedented silicotungstates containing a triangular inorganic Ni(6) core. Furthermore, Na(2)[Ni(6)(μ(3)-OH)(3)(H(2)O)(9)SiW(9)O(34)](2)·17H(2)O (1) presents a rare dimer, in which two SiW(9) units sandwich double Ni(6) cores by W-O-Ni linking instead of conventional Ni-O-Ni.

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...
Ionic Crystal Structures
Most monatomic ions behave as charged spheres, and their attraction for ions of opposite charge is the same in every direction. Consequently, stable structures for ionic compounds result (1) when ions of one charge are surrounded by as many ions as possible of the opposite...
