Abstract:

[Zn2(PCP)(phen)(H2O)F] n 1 and {[Zn 3 (MCP) 2 (phen) 2 (H2O)]2.5H 2O}n 2 (PCP =p-O2C(C6H 4)PO3 3-, MCP = m-O2C(C 6H4)PO3 3- and phen = phenanthroline) were obtained by hydrothermal synthesis and characterized by X-ray single-crystal diffraction. Compound 1 crystallizes in the monoclinic P21/c space group with a = 7.908(2), b = 20.254(3), c = 13.477(2) Å, β = 107.76(3)°, V = 2055.7(8) Å3, Z = 4, C20H16FN2O6PZn2, Mr = 561.10, Dc = 1.813 g/cm3, μ = 2.463 mm-1, F(000) = 1128, the final R = 0.0340 and wR = 0.0794. Compound 2 crystallizes in the monoclinic P21/n space group with a = 15.629(3), b = 18.141(4), c = 17.723(7) Å, β = 121.89(2)°, V = 4267(2) Å3, Z = 4, C40H31N4O13.5P2Zn3, Mr = 1041.70, Dc = 1.620 g/cm3, μ = 1.818 mm -1, F(000) = 2108, the final R = 0.0669 and wR = 0.1775. In compound 1, the tetranuclear Zn4 units are linked together by μ 4-PCP 3- to build 2D (4,4) layers, which are further interconnected through the μ 2-bridging fluorion into a 3D framework with 1D phen ligands-filled channels. As for the 3D supramolecular framework of 2, the novel hexanuclear Zn6 units with "chair" conformation are extended by the moieties of μ 4-MCP3- ligand to a 2D (4,4) layer on the bc plane, which is viewed as the 2-folded layers in 1. In both compounds, the structures are stabilized by hydrogen bonding interactions and π-π stacking interactions between the phen rings. Additionally, FT-IR spectroscopy and the fluorescent properties are discussed.
