title: Hierarchically ordered homochiral metal-organic frameworks built from exceptionally large rectangles and squares.
abstract: Hierarchically ordered homochiral metal-organic frameworks were built from the Cu(II) connecting point and the new (R)-6,6'-dichloro-2,2'-diethoxy-1,1'-binaphthyl-4,4'-bis(p-ethynylpyridine) bridging ligand (L). [Cu(3)L(4)(DMF)(6)(H(2)O)(3)(ClO(4))][ClO(4)](5).10DMF.10EtOH.7H(2)O (1) adopts a unique three-dimensional framework structure via simultaneous interlocking and interpenetration of one-dimensional ladders formed by linking rectangles of 24.8 x 48.6 A(2) in dimensions, whereas [Cu(3)L(5)(DMF)(8)][ClO(4)](6).6DMF.8EtOH.Et(2)O.6H(2)O (2) exhibits an interesting network topology by threading two-dimensional coordination square grids with one-dimensional coordination polymers.
