A novel two-dimensional network self-assembled by [Cd(4,4′-azobispyridine)3(H2O)2]n2n+ cations simultaneously through themselves hydrogen-bonding and π–π stacking interactions

A novel complex {[Cd(azpy)3(H2O)2]·2PF6·(azpy)}n (azpy = 4,4′-azobispyridine) was synthesized and characterized. The molecule structure shows that it is composed of an infinite “rod” with open sidearms. Two-dimensional plane network with large rhombic channels ca. 13.7×14.7 Å is constructed by the infinite “rods” with sidearms [Cd(4,4′-azobispyridine)3(H2O)2]n2n+ cations simultaneously through themselves the complementary binary hydrogen-bonding and π–π stacking interactions.
