Abstract:
The energetically favored structures of clusters are determined by the interactions among particles. Using the modified Morse pair potential, which has two parameters that can freely control the interactions at the minimum, short range, and long range, we systematically investigated how the interactions determines the global minimum structures of clusters and gave the structural phase diagram at 0 K for each cluster size at the range 11 ≤ N ≤ 30. Compared to the Morse potential, a number of new structures are found, and some of them are unexpected. The global minimum structures of modified Morse clusters can act as structural bank, which will be helpful in the optimization of certain real clusters.

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...
