• To explore the potential of PO(3)N groupings in supramolecular assembly.

Main Methods:

• Single-crystal X-ray diffraction analysis.
• Spectroscopic characterization (e.g., NMR, IR).
• Computational modeling (optional, depending on study scope).

Main Results:

• The title compound, [Et(2)NH(2)][(EtO)PO(2)(C(6)H(5)NH)], crystallizes as a molecular salt.
• The asymmetric unit contains two cations (diethylammonium) and two anions with PO(3)N groupings.
• A robust two-dimensional network is formed via N-H⋯O hydrogen bonds linking cations and anions.

Conclusions:

• The hydrogen bonding network dictates the supramolecular architecture.
• The PO(3)N moiety serves as an effective building block for extended structures.
• This work contributes to the understanding of crystal engineering principles for novel materials.
