%X Three 3D robust homochiral helical coordination polymers, [Cu(2,2‘,3,3‘-H2odpa)(bpy)] (1), {[Ni4(2,2‘,3,3‘-odpa)2(bpy)4(H2O)4]·(H2O)16} (2), and {[Co4(2,2‘,3,3‘-odpa)2(bpy)4(H2O)4]·(H2O)14} (3), have been hydrothermally synthesized
from a flexible ligand of 2,2‘,3,3‘-odpda (2,2‘,3,3‘-oxydiphthalic dianhydride). Compound 1 crystallized in space
group P3121 and has a rare chiral dense qzd 7.59 topology that incorporates single helical substructures with the
same accessibility, whereas compounds 2 and 3 crystallized in the space group C2 and possessed isostructural
3D chiral open frameworks based on the homochiral 2D sheets and 4,4‘-bpy pillars. TGA and PXRD analyses
show that the porous framework of 2 is stable after the removal of solvent water molecules. In contrast, 3 changed
its structure to an amorphous one because of the simultaneous loss of solvent and coordination water molecules.
1 is nearly paramagnetic, whereas weak ferromagnetic interactions between M(II) (M = Ni, Co) ions have been
found in 2 and 3.
