The reaction of an equimolar mixture of uranyl and lanthanide nitrates with all-cis 1,2,3,4,5,6-cyclohexanehexacarboxylic acid (H(6)L) under hydrothermal conditions gives the isomorphous complexes [UO(2)Ln(HL)(H(2)O)(7)]center dot H(2)O (Ln = Pr, Eu, Tb, Er), which are rare examples of uranyl lanthanide heterometallic species. The three carboxylate groups in equatorial positions on the cyclohexane ring are bound to uranyl ions, thus generating a (63) hexagonal two-dimensional network. One of the carboxylate groups in an axial position dictates the [Ln(H(2)O)(7)](3+) group, resulting in the sheets being decorated by lanthanide ions on both sides.
