Abstract
The manganese（Ⅱ） complex, [Mn(phen)2(4-CPOA)(H2O)]-5H2O (4-CPOAH2=4-carboxyphenoxyacetic acid) has been synthesized and characterized by elemental analyses, IR, TG and single-crystal X-ray diffraction. The crystal is of monoclinic, space group C2/c, with a =27.471(3), b = 18.490(4), c = 14.507(3) A°, β= 115.13(3)°, V= 6671(3) A°^3, Z = 8, Mr= 717.58, Dc=1.429 g/cm^3, μ= 0.462 mm^-1, F(000) = 2984, the final R = 0.0535 and wR = 0.12O0 for 5413 observed reflections with I > 2σ(I). The Mn（Ⅱ） atom is coordinated by one O atom of 4-carboxyphenoxyacetate, four N atoms of two 1,10-phenanthroline and one water molecule, residing in a distorted octahedral environment. A supramolecular network structure is formed by hydrogen bondsand π-π stacking interactions.
