The new angular bridging ligand 2,4′‐(1,4‐phenylene)bispyridine toposelectively forms dinuclear metallacycles with Cd(NO 3 ) 2 and Zn(NO 3 ) 2 . The Cd II helicates associate into an unprecedented three‐dimensional zeolite‐like helical coordination polymer with hexagonal hydrophobic channels with a diameter of about 10 Å (see scheme). These channels, initially occupied by uncoordinated ligand molecules, can be emptied to afford a guest‐free coordination polymer.
