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(4-pyridyl)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) ·CH(3)CH(2)OH 3, (BDHA)(0.5)· (dipy-sul) ·H(2)O 4, (BDHA)(0.5)· (dipy-dis) ·CH(3)CH(2)OH 5 and (THB) · (dipy-ete)(2)·H(2)O 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.
