[Zn(o-bda)(phen)(H2O)] ·H2O (C22H20N2O6Zn) (1) [where o-bda is o-phenylenediacetic acid dianion and phen is 1,10-phenanthroline] crystallizes in triclinic system, space group P1 with a=0.826 5 (4) nm, b=1.0424(5)nm, c=1.238 1(6) nm, α=76.987(9)°,β=70.987(9)°, γ=78.281(8)°, V=0.9728(8) nm3, Z=2, Dc=1.617 g·cm-3,μ=1.308 mm-1 and F(000)=488. Zn(Ⅱ) ion has a distorted trigonal bipyramid coordination geometry formed by two carboxyl O atoms from two different o-bda groups, two N atoms from the phen ligand and one terminal water molecule. Adjacent Zn(Ⅱ) ions are interlinked by o-bda groups into a infinite zigzag chain structure with a Zn…Zn distance of 0.825 6(4) nm. The adjacent zigzag chains may also be paired under direction of supramolecular recognition and attraction through both π-π stacking and hydrogen bonding interactions into molecular zippers,which further interlinked into a three-dimensional supramolecular network by these noncovalent interactions.CCDC:600935.
