摘要
Structures and stabilities of (OsnN)(0,+/-) clusters have been systematically studied via using density functional theory (DFT) with generalized gradient approximation (GGA). The calculations show that the stable configurations of (OsnN)(0,+/-) are such structures with one N atom bonded to the external of the basic constructions consisting of Os atoms. Meanwhile, (OsnN)(0,+/-) clusters (n = 7-9) represent "magic number" effect, and 8 is the magic number. Additionally, the ground-state structures of (Os8N)(0,+/-) clusters have the best stability, while that of Os7N cluster possesses the worst stability. The result of the study on the ionization potential (IP) and the electron affinity (EA) shows that there are not topological differences among the configurations of (OsnN)(0,+/-) (n = 7-11) clusters.
