Naphthalimide-based ligands have received significant attention for their ability to act as secondary building units for metal containing network structures. The potentially bridging 1,2,4-triazole containing N-(1,2,4-triazolyl)-1,8-naphthalimide (L1) and N-(1,2,4-triazolyl)-4-dimethylamino-1,8-naphthalimide (L2) were prepared, characterized, and complexed with Cu(II) salts. L1 resulted in crystallographically characterized dinuclear complexes, [Cu2(L1)4(NO3)4] and [Cu2(L1)2(OAc)4] when reacted with Cu(NO3)2 and Cu2(OAc)4, respectively. Packing interactions are dominated by π?π and anion?π interactions and gave rise to structure extension through weak supramolecular interactions. Solid state EPR and magnetism measurements on [Cu2(L1)4(NO3)4] revealed the expected values for a non-magnetically coupled square-based pyramidal dimer structure, while [Cu2(L1)2(OAc)4] showed strong anti-ferromagnetic coupling (JCu–Cu?=??185.6?cm?1).
