Abstract The dipole moments of the tetracyclopentadienides, Au(C5H5)4, of the lighter actinoids thorium, uranium and neptunium were measured in benzene solution. Although the compounds in the solid state have a quasi-Td molecular symmetry their dipole moments are not zero, owing to lowering of the molecular symmetry. The origin of the non-zero dipole moments is discussed.

四环戊二烯化物 Au(
C5H5)4 的偶极矩。尽管固态化合物具有准 Td 分子对称性,但由于分子对称性降低,它们的偶极矩不为零。讨论了非零偶极矩的起源。
