  • Infinite double-stranded chains are formed via hydrogen bonds between amide-N and phosphinic-O atoms.
  • Hydrophobic contacts further stabilize the chain structure.

    • Conclusions:

    • The crystal packing is dictated by a combination of strong hydrogen bonds and weaker hydrophobic interactions.
    • The observed structural motifs provide insights into the solid-state behavior of this class of compounds.
