In the title complex, [Cu(C13H11N2O)Cl(C6H8N2)], the CuII atom adopts a distorted tetrahedral geometry being coordinated by the phenolic O atom and the azomethine N atom of the Schiff base ligand N-salicylidene 2-aminopyridine, and by the 2-aminopyridine N atom and a Cl atom. The pyridyl N atom of the Schiff base and the imino N atom of the 4-methyl-pyridine-2-ylimino ligand are not involved in the coordination. There is an intramolecular N-HN hydrogen bond involving the pyridine N atom and the amino group of the 2-aminopyridine ligand. In the crystal, molecules are linked via N-HCl hydrogen bonds, forming chains propagating along .
