A novel Fe(II) coordination polymer [Fe(L)(trans-1,4-chdc)](n) has been hydrothermally synthesized by using 1,4-cyclohexanedicarboxylic acid (1,4-H(2)chdc) and 2-(2-fluorophenyl)-1H-imidazo[4,5-f][1,10]phenanthroline (L). Crystallographic data: monoclinic, space group C2/c with a = 14.571(5), b = 32.389(6), c = 10.948(5) angstrom, beta = 115.186(5)degrees, V = 4676(3) angstrom(3), Z = 8, C27H21FFeN4O4, M-r = 540.33, D-c = 1.535 g/cm(3), F(000) = 2224, mu(MoKa) = 0.697 mm(-1), R = 0.0462 and wR = 0.1110. The two kinds of trans-1,4-chdc ligands link neighboring Fe(II) atoms to yield a two-dimensional layer structure. The pi-pi interactions between the L ligands of neighboring layers result in a three-dimensional supramolecular architecture. The IR and UV-vis spectra of the compound have been investigated in detail.
