| Abstract |
A cobalt (Co) supramolecular triple-stranded helicate, [Co8(PDA)6(Br-PTA)3(DMF)4(H2O)2] (PDA = 2,6-pyridinedicarboxylate, Br-PTA = 5-bromo isophthalate, DMF = dimethylformamide), is successfully synthesized and fully characterized. The solid-state structure of 1 shows that four cobalt atoms are coordinated by three PDA ligands to form a tetranuclear cobalt cluster with three extension points and the ditopic Br-PTA ligands interlink two basic assembly units. Notably, in solid state the cobalt clusters and bromo groups of Br-TSH can function as metallocavitands and guests, respectively, and their corresponding metallocavitand-induced host-guest interaction would account for a unique and highly symmetric cage-like crystal packing geometry, which are rarely observed in other TSHs. The isomorphous molecular cage, which exhibits similar crystal-packing geometry as observed in 1, is also successfully isolated. This is an unusual example of a highly symmetric crystal packing architecture, resulting from the host-guest interaction within metallocavitands of in-situ generated supramolecular modules.
