Figure 2

(a) A pair of D4-symmetric homochiral Δ- and Λ-MOCs-16 showing ΔΔΔΔΔΔΔΔ and ΛΛΛΛΛΛΛΛ configurations of eight RuL3 metalloligands whereas ΛΛΛΛΛΛ- and ΔΔΔΔΔΔ-configurations of six Pd-Py4 subcomponents. (b) A Δ-MOC-16 cage (in space-filling mode) capturing eight S-BINOL guests (in ball-and-stick mode) on the windows pockets. (c) The demonstration how to form D4 Λ-MOC-16 from Oh regular polyhedra by introducing eight Λ-3 metalloligands on the faces of an octahedron, or, on the C3 vertices of a rhombic dodecahedron, to reduce molecular symmetry, and further direct Δ-arrangement of four pyridyl rings around six vertices of Pd centres.
