The title complex, bis(indene-1,2,3-trione 2-oximato)bis(aqua)Mn(Ⅱ), crystallizes in the monoclinic system, space group P21/c with a = 5.201(1), b = 16.547(3), c = 9.914(2) ? ?= 100.30(3), V = 839.4(3) 3, Dc = 1.738 g/cm3, F(000) = 446, C18H12N2O8Mn, Mr = 439.24, m(MoKa) = 0.842 mm-1, Z = 2, the final R = 0.0228 and wR = 0.0782 for 1762 observed reflections (I ≥ 2s(I)). The geometry around Mn(Ⅱ) is a distorted octahedral configuration with the basal plane consisting of two oximo-oxygen and two carbonyl-oxygen atoms from ligand indene-1,2,3-trione 2-oximato, while the axial coordination sites are occupied by two water- oxygen atoms. A plane network is formed by the intermolecular hydrogen bonds. The title complex is the first example of metal complex containing ligand indene-1,2,3-trione 2-oxime. The title complex, bis (indene-1,2,3-trione 2-oximato) bis (aqua) Mn (II), crystallizes in the monoclinic system, space group P21 / c with a = 5.201 (1), b = 16.547 (3) c = 9.914 (2) = 100.30 (3) V = 839.4 (3) 3 Dc = 1.738 g / cm3 F (000) = 446 C18H12N2O8Mn = 439.24 m (MoKa) = 0.842 mm-1, Z = 2, the final R = 0.0228 and wR = 0.0782 for 1762 observed reflections (I ≥ 2s (I)).
