Three zinc(II) complexes containing 4-aminopyridine (4-NH2py) [Zn(4-NH2py)2(NCS)2] (1), [Zn(4-NH2py)2Cl2] (2), and [Zn(4-NH2py)2(NCS)Cl] (3) were synthesized and characterized by FTIR and single crystal X-ray diffraction. All complexes adopt a slightly distorted tetrahedral geometry with different crystal packing. Complex 1 crystallizes in the orthorhombic Pmmn space group, complex 2 in the monoclinic C2/c space group, and complex 3 in the orthorhombic Pbca space group. Non-covalent interactions such as NC-S···H, -Cl···H, and µ-µ stacking interaction between 4-NH2py and other ligands (NCS and Cl) are observed in the crystals packing. In vitro, antibacterial screening of all complexes was evaluated against two bacteria (Escherichia coli and Staphylococcus aureus). The results show that 1 has the highest antibacterial activity than 2 and 3. This difference is due to differences in the interactions elicited by the anion ligands.
