A 3D mixed-valence Cu(I)/Cu(II) coordination polymer constructed by 2-(2-fluorophenyl)-1H-imidazo[4,5-f][1,10]phenanthroline and 1,3-benzenedicarboxylate
A mixed-valence Cu(I)/Cu(II) coordination polymer, namely, [Cu-2(L)(1,3-BDC)](n) (1), has been synthesized under hydrothermal conditions (HL = 2-(2-fluorophenyl)-1H-imidazo[4,5-f][1,10]phenanthroline and 1,3-H2BDC = 1,3-benzenedicarboxylic acid). Its structure has been determined by single crystal X...

| Summary: | A mixed-valence Cu(I)/Cu(II) coordination polymer, namely, [Cu-2(L)(1,3-BDC)](n) (1), has been synthesized under hydrothermal conditions (HL = 2-(2-fluorophenyl)-1H-imidazo[4,5-f][1,10]phenanthroline and 1,3-H2BDC = 1,3-benzenedicarboxylic acid). Its structure has been determined by single crystal X-ray diffraction analysis and powder X-ray diffraction. The crystals are the monoclinic space group P2(1)/c with a = 10.686(4), b = 17.376(8), c = 11.759(4) angstrom, beta = 92.072(14)degrees, C27H14Cu2FN4O4, M-r = 604.50, V = 2182.1(15) angstrom(3), Z = 4, D-calcd. = 1.84 g cm(-3), R = 0.0588 and wR = 0.1202 (all data). In complex 1, the mixed-valence Cu(I)/Cu(II) atoms are linked by L and 1,3-BDC to give a rare 3D (3,3,4)-connected (4.7.9)(7.8.9)(4.7.8.9(3)) framework. The temperature-dependent magnetic susceptibility of 1 was investigated in the temperature range of 2-300 K. |
