To clarify the nature of five-center, six-electron (5c-6e) C(2)Z(2)O interactions, atoms-in-molecules (AIM) analysis has been applied to an anthraquinone, 1,8-(MeZ)(2)ATQ (1 (Z=Se), 2 (Z=S), and 3 (Z=O)), and a 9-methoxyanthracene system, 9-MeO-1,8-(MeZ)(2)ATC (4 (Z=Se), 5 (Z=S), and 6 (Z=O)), as well as 1-(MeZ)ATQ (7 (Z=Se), 8 (Z=S), and 9 (Z=O)) and 9-MeO-1-(MeZ)ATC (10 (Z=Se), 11 (Z=S), and 12 (Z=O))
为了阐明五中心六电子(5c-6e)C(2)Z(2)O相互作用的性质,分子中的原子(AIM)分析已应用于蒽醌1,8-(MeZ )(2)ATQ(1(Z = Se),2(Z = S)和3(Z = O))和9-甲氧基蒽系统9-MeO-1,8-(MeZ)(2) ATC(4(Z = Se),5(Z = S)和6(Z = O))以及1-(MeZ)ATQ(7(Z = Se),8(Z = S)和9(Z = O))和9-MeO-1-(MeZ)ATC(10(Z = Se),11(Z = S)和12(Z = O))。已对5c-6e C(2)Z(2)O和5c-6e C(2)Z(2)O的键临界点(BCP)的总电子能量密度(H(b)(r(c)))进行了测试,这是弱相互作用的适当指标。 1-12中n(p)(O)sigma *(Z--C)类型的3c-4e CZO相互作用。为了便于比较,还对一些氢键加合物进行了重新检查。总电
