The [{Pr(NO3)2(H2O)3}{Pr(NO3)(H2O)4} (C36H36N24O12)](NO3)3·4H2O 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(III) cation. The neodymium(III) complex is the first example of lanthanide compounds with cucurbit[6]uril belonging to coordination polymers.
