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 (L)(1,3-BDC)] ( ), has been synthesized under hydrothermal conditions (HL = 2-(2-fluorophenyl)-1 -imidazo[4,5- ][1,10]phenanthroline and 1,3-H BDC = 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 with = 10.686(4), = 17.376(8), = 11.759(4) Å, = 92.072(14)°, C Cu FN , = 604.50, = 2182.1(15) Å , = 4, = 1.84 g cm , = 0.0588 and = 0.1202 (all data). In complex , 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 ) framework. The temperature-dependent magnetic susceptibility of was investigated in the temperature range of 2–300 K.
