摘要
A novel metal-organic framework, namely [Zn(C20H13O5P)](n) (1), has been hydrothermally synthesized through the reaction of 5-(oxidediphenylphosphino)isophthalic acid (H2L) with Zn(II) salt. The title compound crystallizes in monoclinic, space group P2(1)/c with a = 11.0966(10), b = 14.5651(14), c = 14.7311(15) angstrom, beta = 130.022(6)degrees, C20H13O5PZn, M-r = 429.64, V = 1823.3(3) angstrom(3), D-c = 1.565 g/cm(3), F(000) = 872, mu = 1.463 mm(-1), S = 1.054 and Z = 4. The final R = 0.0270 and wR = 0.0739 for 2769 observed reflections with I > 2 sigma(I). In the title complex, the Zn-2(CO2)(2) binuclear clusters are linked by L2- ligands to result in a pillared layer structure in the bc plane, which is a (4,4)-net composed of helical chains with opposite chirality by sharing Zn-2(CO2)(2) units. Adjacent layers are further associated together through Zn-O bonds involving the metal center and the oxygen atom of P=0 group to achieve a 3D architecture, in which one-dimensional quadrangled channel displays the interweaving of two pairs of coaxial double-helical chains with opposite chirality. The luminescence property and thermogravimetric analysis of the title complex were investigated.
