| 摘 要： | 用密度泛函理论(DFT)的B3LYP方法, 在6-31G*水平上对(BCO)+n(n=1-12)团簇的几何结构、电子结构、振动频率等性质进行了理论研究. 结果表明, (BCO)+n团簇的基态结构均为羰基端配位(μ1-CO)结构, 且含三元环和五元环数目越多或四元环和六元环的数目越少, 相应的结构越稳定. 能量分析得到, n 为奇数的(BCO)+n团簇比n为偶数的稳定.

| Abstract: | The geometric configurations, electronic structures and vibrational frequencies of the (BCO)_n~ (n=1-12) were calculated with B3LYP method at 6-31G* level. The result revealed that the ground states of the clusters favor three- and five-member rings and disfavored four- and six-member rings in the framework, in which all the carbonyls were terminal. Energy analysis exhibited that the (BCO)_n~ with odd n was more stable than that with even n. |
