A novel zinc(Ⅱ) metal phosphonate compound [Zn(phen)(m-OOCC6H4PO3H)] 1(phen=phenanthroline) has been synthesized under hydrothermal conditions.Single-crystal X-ray structure analysis reveals that compound 1 belongs to the triclinic system,space group P1 with a=9.3356(19),b=10.203(2),c=10.743(2) (A),α=76.3030(70),β=69.2317(51),γ=84.3833(74)°,V =929.4(3) (A)3,Z=2,C20H15N2O5PZn,Mr=459.68,Dc=1.643 g/cm3,μ=1.444mm-1,F(000)=468,the final R=0.0330 and wR=0.0848.In the structure,the central ion Zn(Ⅱ) is five-coordinated,linking three O atoms with one from carboxyl and the other two from phosphonyl group.The remained two coordinate sites were occupied by two N atoms from one phen molecule to form the asymmetric unit.Then every two adjacent asymmetric units are bridged by the O atoms from phosphonate group and carboxyl to give rise to a 1D chain along the b axis.These chains are constructed by weak π-π stacking interactions and C-H…π interactions to generate a 3D supramolecular framework.
