Abstract: A Manganese(Ⅱ) complex [Mn(NPA)2(Phcccccccen)(H2O)2] has been synthesized x(NPA=N-phenylanthr-anilic acid, Phen=1,10-phenanthroline) and characterized by IR, UV, elemental analysis, thermal analysis and X-ray diffraction methods. It Crystallizes in Monoclinic system, space group C2/c with a=2.790 5(8) nm, b=1.019 0(4) nm, c=1.228 0(4) nm, β=101.803(11)°, V=3.417 7(19) nm3, Z=4, Dc=1.352 g·cm-3, F(000)=1 444, R1=0.044 4, wR=0.124 2. The crystal structure shows that the Mn(Ⅱ) ion is coordinated with two oxygen atoms from two N-phenylanthranilic acid, two Nitrogen atoms from one 1,10-phenanthroline, two oxygen atoms from two water respectively, forming a distorted octahedral coordination geometry.
