The intra-and intermolecular interactions responsible for the stability of our compound within the crystal lattice have been thoroughly discussed. FT-IR spectroscopic analyses have confirmed the well atomic organization and stability of our compound. Using the RDG and NCI approaches, we identified strong N\u2014H\u00b7\u00b7\u00b7O and O\u2014H\u00b7\u00b7\u00b7H hydrogen bonds, along with notable van der Waals (vdW) interactions between the cationic units and the phosphate anion, confirming the key role of non-covalent forces in stabilizing the crystal structure. Intermolecular interactions were further elucidated by Hirshfeld surface analysis. Moreover, dispersion-corrected Density Functional Theory provided insights into chemical reactivity properties. The compound was also analyzed using solid-state spectroscopies. This contribution enhances the understanding of the structural diversity of organic-dihydrogenphosphate compounds.\n                  <\/jats:p>","DOI":"10.3389\/fchem.2025.1701702","type":"journal-article","created":{"date-parts":[[2025,11,17]],"date-time":"2025-11-17T11:29:16Z","timestamp":1763378956000},"update-policy":"https:\/\/doi.org\/10.3389\/crossmark-policy","source":"Crossref","is-referenced-by-count":12,"title":["Synthesis, structural characterization, spectroscopic analyses, DFT-modeling, and RDG-NCI assessment of 4-dimethylaminopyridinium dihydrogen monophosphate"],"prefix":"10.3389","volume":"13","author":[{"given":"Lelfia","family":"Guelmami","sequence":"first","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Mondher","family":"Dhifet","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Khadija","family":"Zaki","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Norah","family":"Alwadai","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Hammadi","family":"Khmissi","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Mohamed","family":"Bouzidi","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Bouzid","family":"Gassoumi","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Mohammed","family":"Bouachrine","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"1965","published-online":{"date-parts":[[2025,11,17]]},"reference":[{"key":"B1","doi-asserted-by":"publisher","first-page":"1894","DOI":"10.1107\/S0108270187089716","article-title":"Structures of ethylenediammonium monohydrogentetraoxophosphate (V) and ethylenediammonium monohydrogentetraoxoarsenate (V)","author":"Averbuch-pouchot","year":"1987","journal-title":"Acta Cryst."},{"key":"B2","doi-asserted-by":"publisher","first-page":"99","DOI":"10.1107\/S0108270187008539","article-title":"Structures of glycine monophosphate and glycine cyclo-triphosphate","author":"Averbuch-Pouchot","year":"1988","journal-title":"Acta Cryst."},{"key":"B3","doi-asserted-by":"publisher","first-page":"421","DOI":"10.1107\/S0108270188011977","article-title":"Structure of ethylenediammonium dihydrogentetraoxophosphate (V) pentahydrogenbis [tetraoxophosphate (V)]","author":"Averbuch-pouchot","year":"1989","journal-title":"Acta Cryst."},{"key":"B4","doi-asserted-by":"publisher","first-page":"1642","DOI":"10.1107\/S0108270191001518","article-title":"Structure of 4-aminopyridinium dihydrogentetraoxophosphate (V) monohydrate","author":"Bagieu-Beucher","year":"1991","journal-title":"Acta Cryst."},{"key":"B5","doi-asserted-by":"publisher","first-page":"238","DOI":"10.1107\/S0108270189006177","article-title":"Structure of cytosinium dihydrogenmonophosphate","author":"Bagieu-Beucher","year":"1990","journal-title":"Acta Cryst."},{"key":"B6","doi-asserted-by":"publisher","first-page":"277","DOI":"10.1016\/j.saa.2014.01.023","article-title":"Thermal and magnetic properties and vibrational analysis of 4-(dimethylamino) pyridine: a quantum chemical approach","volume":"124","author":"Balachandran","year":"2014","journal-title":"Spectrochim.
