A number of new copper(II) complexes of 2-(N-tosylamino)benzaldehyde benzoylhydrazone (H2L) CuLLn (n = 1–6) with heterocyclic donor ligands (L1 = 1-propyl-2-aminobenzimidazole, L2 = 1‑hexyl-2-aminobenzimidazole, L3 = 1-octyl-2-aminobenzimidazole, L4 = 2,2'-bipyridine, L5 = 1,10-phenanthroline, and L6 = 2-aminopyridine) is synthesized. The structures and compositions of the synthesized compounds are determined by elemental analysis, 1Н NMR spectroscopy, IR spectroscopy, and magnetochemistry. The molecular structures of complexes CuLL1,2,4−6 are determined by XRD (CIF files CCDC nos. 2341480 (CuLL1), 2341468 (CuLL2), 2341478 (CuLL4), 2341477 (CuLL5), and 2341479 (CuLL6)). The biological activity of the complexes is studied. The adducts with L1, L2, and L6 exhibit a significantly higher anti-protist activity than chloroquine used as the reference compound.
