Crystal Engineering Based on Polymeric Hydrogen-Bonded Supramolecules by Self-Assembling of 9, 10-Bis(3,5-dihydroxyphenyl)anthracene and 2,2′,4,4′-Tetrahydroxybenzophenone with Bipyridines

9, 10-bis(3,5-dihydroxyphenyl)anthracene (BDHA) and 2,2′,4,4′tetrahydroxybenzophenone (THB) are crystallized with bipyridine bases 4,4 ́-bipyridyl (bipy), 1,2-bis(4-pyridyl)ethane (bipy-eta), 1,2-di(4-pyridyl)ethylene (dipy-ete), 1,3-di(4pyridyl)propane (dipy-pra), 4,4 ́-dipyridyl sulfide (dipy-sul), and 4,4 ́-dipyridyl disulfide (dipy-dis) to afford molecular complexes (BDHA)·(bipy)2 1, (BDHA)·(bipy-eta)2 2, (BDHA)0.5·(dipy-pra)·CH3CH2OH 3, (BDHA)0.5·(dipy-sul)·H2O 4, (BDHA)0.5·(dipydis)·CH3CH2OH 5 and (THB)·(dipy-ete)2·H2O 6. The crystal structures of 1–6 have been determined by single-crystal X-ray diffraction. All these molecular complexes exhibit polymeric supramolecular structures via O–H···N or O–H···O hydrogen-bonding. 1 and 2 form infinitely rectangular macrocycles linked with one another, whose sizes are ca.12.477 Å × 4.802 Å and ca.14.575 Å × 4.809 Å, respectively. 3, 5 and 6 form the one-dimensional zigzag chain structure. 4 forms a ladder structure, and two dipy-sul molecules were included in a frame.
