A new Eu(II)-based complex [H2N(Me)2][Eu3(L)2(HCOO)2(DMF)2(H2O)](I) (H4L = 3,5'-di(3',5'-dicarboxylphenyl)pyridine) has been synthesized and structurally characterized. Single-crystal X-ray analysis (CIF file CCDC no. 1559225) reveals that compound I has 3D (4.62)(4.62)(42.67.86) topology. The emission spectra of I is dominated by four characteristic bands and shows strong luminescent feature. Furthermore, the photocatalytic properties of I for degradation of the methyl violet and Rhodamine B have been explored.
