ditantalum hydride complex undergoes head-to-head C-C coupling of six CO molecules undermildconditions to produce an octaanionic C(6)O(6) unit. During the reaction, eight-electron reduction of six CO molecules takes place. In the product, the C(6)O(6) unit is coordinated to four tantalum metals through six oxygen and two carbonatoms. The geometrical parameters within the Ta(4)C(6)O(6) core indicate
二钽氢化物复合物在温和条件下经历六个 CO 分子的头对头 CC 耦合,以产生一个八阴离子 C(6)O(6) 单元。在反应过程中,发生了六个 CO 分子的八电子还原。在产品中,C(6)O(6) 单元通过六个氧原子和两个碳原子与四种钽金属相协调。Ta(4)C(6)O(6) 核心内的几何参数表明来自己三烯-hexolate 形式的重大贡献。
