New organic-inorganic hybrid ionic material Tris(melaminium) monodrogenphosphate dihydrogenphosphate tetrahydrate: synthesis, single-crystal structure, Hirshfeld surface analysis, spectroscopic characterization, and thermal behavior

Résumé

A novel type-I hybrid ionic material named Tris (melaminium) monodrogenphosphate dihydrogenphosphate tetrahydrate (3C3H7N6+.HPO42−.H2PO4−.4H2O) was synthesized. Its structure was affined by single crystal X-ray diffraction, illustrating that the material crystallizes in P1− triclinic system with cell parameters a = 11.2424(9)Å, b = 11.8460(9)Å, c = 11.983(9)Å, α = 66.929(3)°, β = 71.555(3)° and γ = 64.303(3)° and a filling rate Z = 2. The 3D-supramolecular network is constituted by non-stacked planar melaminium chains, laid along a diagonal direction of the unit cell, and joined indirectly via the inorganic part's molecules, forming lamellar material along Oc-direction; the various contacts were discussed through 3D-Hirshfeld surface analysis. The UV–visible spectroscopy reveals that this hybrid material is transparent in the visible and UV near visible domains, and has considerable absorption in middle and far UV. The several vibration modes were analyzed by FT-IR spectroscopy and correlated to the functional groups of the affined structure. The thermal decomposition behavior was studied by TGA/DTG and DSC techniques exhibiting a good thermal stability of 340°C.
