摘要
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 P2(1)/c, the cell parameters (angstrom, degrees): [a = 6.2959(2), b = 9.5613(3), c = 12.7942(4), beta = 92.718(3), V = 769.31(4) angstrom(3) and Z = 2]. 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 main contributions are provided by O center dot center dot center dot H/H center dot center dot center dot O contacts. The Fourier Transform Infrared spectroscopy shows the expected bands of piperazine and phosphate groups. The catalytic efficiency was tested with the reduction reaction of the three nitrophenol isomers (paranitrophenol 4-NP, metanitrophenol 3-NP and orthonitrophenol 2-NP), and was applied as an oxidant for the degradation of methylene blue in aqueous solutions.
