a Molecular structure of FIR-151. b Topological representation of FIR-151, with spheres denoting Ti atoms (vertices) and rods representing Ti-Ti edges. The Ti12 (6-4-6) module is highlighted in red. c Graphical representations of the truncated octahedron and its corresponding net, composed of six squares and eight hexagons. Molecular structures of the intermediate species and kinetic trapper: the Ti12 macrocycle (intermediate 1, d the Ni3Cl4 cluster (kinetic trapper, e and Ti12 (6-4-6) modular (intermediate 2, f). g Proposed hierarchical assembly mechanism of the truncated octahedral-type MOP. Atom colors: Ti, sky blue; Ni, purple; C, gray; O, red; Cl, green; N, blue. All hydrogen atoms are omitted for clarity.
