Abstract

Crystal structure analysis shows the cucurbit[6]uril host and its tetrahydrofuran (THF) guest in the Pmn21 crystal lattice. The crystal data and refinement parameter for the title compound are: a = 14.027(3), b = 11.807(3), c = 16.760(4) Å, V = 2774.7(9) Å3. For Z = 2 and Mw = 1529.52, the calculate density Dcal = 1.825 g/cm3. Hydrogen bonding interaction assembled the adjacent {[La(H2O)6Cl](C4H8O@C36H36N24O12)}2+ cations into a novel one-dimensional superamolecular chain.

Synopsis

A new coordination complex, {[La(H2O)6Cl](C4H8O@C36H36N24O12)}(H2O)2(NO3)2, in which a THF molecule is encapsulated, is synthesized and characterized. Interestingly, the coordination complex serves as large building block for the construction of a novel one-dimensional supramolecular compound.
