compounds 3 and 4 were synthesized by reaction of 1,1′ ferrocenylenediol with the Co triple decker compounds [(η5-Me5C5)Co}2(η6:η6-toluene)] and [(η5-EtMe4C5)Co}2(η6:η6-toluene)], respectively. The central Co atom of 3 is coordinated by five O atoms in a square-pyramidal manner. The remaining two Co atoms of 3 are coordinated to a Me5C5 ligand in a η5-fashion and by the two O atoms of two 1,1′ ferrocenylenediolato
标题化合物3和4是由1,1'ferrocenylenediol的反应与联合三重双层化合物合成[(η 5 -Me 5 Ç 5)有限} 2(η 6:η 6 -甲苯)]和[( η 5 -EtMe 4 ç 5)有限} 2(η 6:η 6 -甲苯)]中。的中心钴原子3是通过在四方锥方式5个O原子配位。中的其余两个Co原子3被配位到我5 Ç 5配位体在一个η 5-形成并通过两个1,1'二茂铁基亚乙基二醇基配体的两个O原子作为螯合配体。在4,中央钴原子配位到ferrocenylenediolato在三角棱柱形的方式配体3的所有六个O原子,而两个其它的Co原子由一个EtMe协调4 Ç 5配位体在一个η 5 -时尚和由三个氧三个二茂铁基乙二醇配体的原子导致4的整体三体结构。
