（Cot）（2）Th（L）（L = py，4，4 '-bipy，tBuNC，phen，Me（4）phen）与中性单齿或双齿刘易斯碱反应，生成夹心状配合物（Cot）（2）Th（L）。在气相中的DFT计算表明，对于U和Th，弯曲化合物（Cot）（2）An（L）的形成应该是容易的，线性和弯曲形式的能量接近。
In stark contrast to uranocene, (Cot)(2)Th reacts with neutral mono- or bidentate Lewis bases to give the bent sandwich complexes (Cot)(2)Th(L) (L = py, 4,4'-bipy, tBuNC, phen, Me(4)phen). DFT calculations in the gas phase show that, for both U and Th, formation of the bent compound (Cot)(2)An(L) should be facile, the linear and bent forms being close in energy.
