Abstract
A novel 2D coordination polymer, [Mn(pyphen)(L)] (1) (L=3-carboxy-1-(4'-(2''- carboxy)biphenylmethyl)-2-oxidopyridinium and pyphen=pyrazino[2,3- f ][1,10]phenanthroline), has been synthesized under hydrothermal conditions, and characterized by elemental analysis, IR, UV/Vis spectra and its optical band gap. Crystal data for 1: C34H21MnN5O5, monoclinic, space group P21/c, a=12.484(4), b=13.473(5), c=16.479(3) Å, b =99.618(6)° , V =2732.8(14) Å3, Z =4. In 1, each L ligand coordinates to three Mn(II) atoms through its two carboxylate groups and one phenolate unit. In this way, L2- ligands link neighboring Mn(II) atoms to generate a layer structure.
