The organometallic tris-cyclopentadienide actinide(III) (AnCp ) complexes were first reported about 50 years ago. However, up until now, only the NpCp solid state structure has been studied. Here we report on the solid state structures of UCp and PuCp which are isostructural to the Np analogue. The structural models are supported by theoretical calculations and compared to their lanthanide analogues. The observed trends in changes of bond lengths might be indicator for an increased covalency in the bonding in the tris-cyclopentadienide actinide(III) complexes (AnCp ) compared to their lanthanide homologues.
有机金属三茂锕系元素(III)（AnCp ）配合物大约在50年前首次被报道。然而，直到现在，仅对NpCp的固态结构进行了研究。在此我们报道了与Np类似物同构的UCp和PuCp的固态结构。这些结构模型得到了理论计算的支持，并与它们的镧系类似物进行了比较。观察到的键长变化趋势可能表明，与镧系同系物相比，三茂锕系元素(III)配合物（AnCp ）中的键合共价性增加。
