A new hybrid phosphate (C4H12N2)[Co(H2O)6](HPO4)2 has been synthesized using wet chemistry. The compound crystallizes in the monoclinic system, space group P21/c. Its crystal packing is made of isolated [Co(H2O)6] octahedra, regular [PO3(OH)] tetrahedra and diprotonated piperazine [C4H12N2]2+, which interact through hydrogen bonds. The Hirshfeld surface and 2D fingerprint plots have been performed to explore the features of the crystal cohesion. The Fourier Transform Infrared spectroscopy shows the expected bands of piperazine and phosphate groups. The catalytic efficiency was tested with the red uction reaction of the three nitrophenol isomers and was applied as an oxidant for the degradation of methylene blue in aqueous solutions.
