The complex {[Cu(4,4′-bpy)(pyz)(H2O)2][PF6]2}n comprising two-dimensional rectangular grids with each cavity enclosed by two 4,4′-bipyridine (4,4′-bipy) and two pyrazine (pyz) ligands, which superpose in an off-set fashion to give smaller rectangular channels, has been prepared and characterized by single-crystal X-ray structural analysis.
