The chiral 3D MOFs resulted from the packing of chiral 1D SBBs were studied. It was demonstrated that the final packing pattern is sensitively dependent on the dimension of SBBs. In addition, we were able to identify a new plywood-like network from ligand 2H₂ exhibiting an unprecedented six-way chiral helical packing motif, which extends the list of invariant rod packings.
