Synthesis and characterization of two novel lanthanide coordination polymers with an open framework based on an unprecedented [Ln(7)(micro(3)-OH)(8)](13+) cluster.
Two novel heptanuclear lanthanide clusters of the dicubane-like type [Ln(7)(micro(3)-OH)(8)](13+) (Ln = Ho (1), Yb (2)) were obtained via hydrothermal reaction, and as building blocks, they were formally assembled into porous three-dimensional networks through the linkage of 1,4-naphthalenedicarboxylate (1,4-NDA), forming first examples of porous lanthanide polymers with 1,4-NDA, [Ln(7)(micro(3)-OH)(8)(1,4-NDA)(6)(OH)(0.5)(Ac)(0.5)(H(2)O)(7)].4H(2)O (Ln = Ho, Yb). The coordinating water molecules and lattice water molecules are enclathrated in the cavities.
