View down the direction of [Cu(nor)2]SO4·7H2O, showing the layered arrangement parallel to the (010) plane of intercalated slabs of [Cu(nor)2]2+ complexes and hydrated SO42− ions, and the hydrogen-bonding network for H⋯A < 2 Å. Layers of the same kind are symmetry-related through a twofold screw axis along the unique b axis of space group P21/c. |
