Cyclic water-trimer encapsulation into D2(22)-C84 fullerene

Small cyclic water drop in a molecular barrel: Computations predict that the cyclic water trimer can be encapsulated into the most common C84 fullerene cage, the encapsulated cyclic trimer has cis-organization of H atoms not involved in the hydrogen bonds, i.e., different from the trans arrangement known for the free water trimer.67
