The single-crystal X-ray diffraction studies revealed that 1 and 2 are isostructural and display 3D network which are based on [Co2(μ2-H2O)] units. The photocatalyticactivities of 1 and 2 have been checked for the photodegradation of methyl violet (MV) under UV light. The results indicate that the MOFs studied are stable and good candidates for as photocatalysts for dye degradation. The plausible mechanism of photocatalytic properties have been proposed through density of states (DOS) calculations. Magnetic studies for both the 1 and 2 reveal the dominant antiferromagneticcoupling between the Co(II) ions.Graphical abstractThe photocatalytic activities and magnetic properties of two new Co(II)-based MOFs have been explored. The plausible mechanism of them displayed photocatalytic properties have been proposed through density of states (DOS) calculations.
