Hierarchically Ordered Homochiral Metal−Organic Frameworks Built from Exceptionally Large Rectangles and Squares

Hierarchically ordered homochiral metal−organic frameworks were built from the CuII connecting point and the new (R)-6,6′-dichloro-2,2′-diethoxy-1,1′-binaphthyl-4,4′-bis(p-ethynylpyridine) bridging ligand (L). [Cu3L4(DMF)6(H2O)3(ClO4)][ClO4]5·10DMF·10EtOH·7H2O (1) adopts a unique three-dimensional framework structure via simultaneous interlocking and interpenetration of one-dimensional ladders formed by linking rectangles of 24.8 × 48.6 Å2 in dimensions, whereas [Cu3L5(DMF)8][ClO4]6·6DMF·8EtOH·Et2O·6H2O (2) exhibits an interesting network topology by threading two-dimensional coordination square grids with one-dimensional coordination polymers.
