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(μ_1-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. 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.
