The reactions of anthraquinone‐2,6‐disulfonic acid disodium salt (Na 2 a‐2,6‐dad) with Cu II , Mn II , and Zn II with 1,10‐phenanthroline (phen) or 2,2′‐dipyridyl (bipy) under hydrothermal conditions formed two or three‐dimensional supramolecules of stoichiometries [Cu(a‐2,6‐dad)(phen)(H 2 O) 3 ](H 2 O) 4 ( 1 ), [Mn(a‐2,6‐dad)(bipy) 2 (H 2 O)](H 2 O) 2 ( 2 ), and [Zn(a‐2,6‐dad)(bipy) 2 (H 2 O)](H 2 O) 2 ( 3 ), which were synthesized and characterized. The arrangement around each metal atom is distorted octahedral. The ligands in all the compounds are engaged in intermolecular hydrogen bonding leading to the formation of hydrogen‐bonded networks, the compounds show novel π–π stacking interactions. Photoluminescence measurements indicate that the compound [Zn(a‐2,6‐dad)(bipy) 2 (H 2 O)](H 2 O) 2 ( 3 ) shows strong blue luminescence in the solid state at room temperature.
