Zhan-Lin Xu, Shuai Ma, Yu He, Zhi-Guo Kong

Abstract

The new coordination polymer [Cd(oct)(L)] (H2oct = octanedioic acid and L = 2-(4-fluorophenyl)-1H-imidazo- [4,5-f][1,10]phenanthroline) has been synthesized under hydrothermal condition and characterized by elemental analysis, IR spectroscopy and single-crystal X-ray diffraction. Crystal data: C27H23CdFN4O4, monoclinic, space group C2/c, a = 21.391(4), b = 18.180(4), c = 14.031(3) Å , β = 116.50(3), V = 4883(2) Å3, Z = 8. The flexible oct dianions bridge the Cd(II) cations to yield a double-chain structure. The L ligands are attached on both sides of the chains, and their π-π interactions between neighboring chains result in two-dimensional supramolecular layers
