摘要：
The [{Pr(NO3)(2)(H2O)(3)}{Pr(NO3)(H2O)(4)}(C36H36N24O12)](NO3)(3)center dot 4H(2)O and [{Nd(NO3)(H2O)(4)}(2)(NO3@C36H36N24O12)][Nd(NO3)(6)] complexes were prepared by heating a mixture of lanthanide nitrates, cucurbit[6]uril, and water in a sealed tube. X-ray diffraction study demonstrated that the metal atoms in the former complex are linked to the macrocycle through tridentate coordination of the portal oxygen atoms of cucurbit[6]uril to the praseodymium(m) cation. The neodymium(m) complex is the first example of lanthanide compounds with cucurbit[6]uril belonging to coordination polymers.
