Hydrothermal synthesis and crystal structure of supermolecular compound [Zn(H_2O)_6](ada)(bipy)

A new 3D supramolecular compound [Zn(H2O)6](ada)(bipy) was obtained through the hydrothermal reaction of zinc(Ⅱ) acetate with mixed ligands——sodium anthraquinone-2,6-disulfonate(Na2ada) and 4,4-bipyridine(bipy), and the product was characterized by elemental analysis and X-ray diffractometry.The test results revealed that the compound belonged to a triclinic system with a P-1 space group,and the cell parameters were a=0.764 8(2) nm,b=1.172 3(3) nm,c=1.583 7(5) nm,α=103.150(6)°,β=90.450(5)°,and γ=92.815(5)°.The structural analysis of the compounds indicates that there are multiple hydrogen bonding and π…π stacking interactions between the aromatic molecules,and the 3D supramolecular network of the title compound is formed through hydrogen and π…π stacking interactions.
