Abstract
Wu (Reports, 31 August 2018, p. 912) claim that recently characterized octacarbonyls of Ca, Sr, and Ba mimic the classical Dewar-Chatt-Duncanson bonding motif of transition metals. This claim, which contradicts known chemistry and computed electron density distributions, originates in the assumption of a flawed reference state for energy decomposition analyses.
摘要
吴（《报告》，2018年8月31日，第912页）声称，最近表征的钙、锶和钡的八羰基化合物模仿了过渡金属经典的杜瓦-查特-邓卡森成键模式。这一与已知化学和计算出的电子密度分布相矛盾的说法，源于对能量分解分析采用了有缺陷的参考态这一假设。
