A close-packed Ti6 and Ti12 nanocluster superstructure†
Abstract
A close-packed superstructure consisting of Ti12 and Ti6 in one single crystal is prepared via a solvothermal synthesis. The closest twelve neighboring Ti6 clusters form a distorted cuboctahedron centered with a Ti12 cluster. Such a structure imitates the stacking sequence of a face-centered cubic (FCC) metal. By employing the cuboctahedron as a basic unit, the whole single crystal is re-rendered.
