Abstract:
[Zn(2)(PCP)(phen)(H(2)O)F](n) 1 and {[Zn(3)(MCP)(2)(phen())2(H(2)O)]center dot 2.5H(2)O}(n) 2 (PCP (=) p-O(2)C(C(6)H(4))PO(3)(3-), MCP = m-O(2)C(C(6)H(4))PO(3)(3-) and phen = phenanthroline) were obtained by hydrothermal synthesis and characterized by X-ray single-crystal diffraction. Compound 1 crystallizes in the monoclinic P2(1)/c space group with a = 7.908(2), b = 20.254(3), c = 13.477(2) angstrom, beta = 107.76(3)degrees, V = 2055.7(8) angstrom(3), Z = 4, C(20)H(16)FN(2)O(6)PZn(2), M(r) = 561.10, D(c) = 1.813 g/cm(3), mu = 2.463 mm(-1), F(000) = 1128, the final R = 0.0340 and wR = 0.0794. Compound 2 crystallizes in the monoclinic P2(1)/n space group with a = 15.629(3), b = 18.141(4), c = 17.723(7) angstrom, beta = 121.89(2)degrees, V = 4267(2) angstrom(3), Z = 4, C(40)H(31)N(4)O(13.5)P(2)Zn(3), M(r) = 1041.70, D(c) = 1.620 g/cm(3), mu = 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 mu(4)-PCP(3-) to build 2D (4,4) layers, which are further interconnected through the mu(2)-bridging fluorion into a 3D framework with ID 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 mu(4)-MCP(3-) 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 pi-pi stacking interactions between the phen rings. Additionally, FT-IR spectroscopy and the fluorescent properties are discussed.
