摘 要:The title complex Mn(H2O)2(HNic)2 (C22H12MnN2O8, Mr = 367.18) crystallizes in monoclinic, space group P21/c with a = 7.5735(8), b = 12.5295(13), c = 7.6466(8)A.β = 101.2790(10)°, Z = 2, V= 711.59(13) A^3, D, = 1.714 g/cm^3,μ(MoKa) = 0.974 mm^-1, F(000) = 374, R1 (1255 observed reflections (Ⅰ 〉 2σ(Ⅰ)) = 0.0250) and wR2 = 0.0662 (all data). In this paper, we report the complexation of Mn(Ⅱ) by the bidentate ligand 2-hydroxynicotinic acid (HNic). In the crystal the Mn(Ⅱ) ion exhibits a deformed octahedron structure. The title complex Mn(H2O)2(HNic)2 has a three-dimensional (3D) network structure extended by hydrogen bonds, which are formed by two typical eight-membered hydrogen-bonded rings.
