Synthesized crystal of Hexa (4‐aminopyridine) triscopper(II) carbonate trihydrate with the chemical formula C33 H42 Cu3 N12 O12. Molecular structure of synthesized compound determined by single crystal X‐ray diffraction (SCXRD) of Hexa (4‐aminopyridine) triscopper(II) carbonate trihydrate. The 4‐aminopyridine molecular is bonded with copper atoms via the aromatic ring's nitrogen atoms (Cu‐N). The analysis of the Hirshfeld surface is essential to the crystal packing process because of the intermolecular interactions. Intermolecular interactions of hydrogen bonds are revealed through Hirshfeld surface analysis viewed by 3D and 2D fingerprint plots. A novel organic‐inorganic hybrid crystal is Hexa (4‐aminopyridine) triscopper(II) carbonate trihydrate determined, and their study of this crystal reveals various intermolecular interactions responsible for crystal stability.
