A new heterometallic complex containing bis-Schiff base, namely, [(Salbn)NiNa(DMF)(H2O)]·N(CN)2 (1) (Salbn = bis(3-methoxysalicylidene) benzene-1, 2-diamine, DMF = N, N-dimethyl formamide) has been prepared through one-pot refluxing and condensation approach. Complex 1 was characterized by elemental analysis, IR spectroscopy, X-ray single-crystal diffraction, and powder X-ray diffraction analysis. The intermolecular hydrogen bonding interaction connects the Schiff base complex units through the [N(CN)2]− anion into dimer aggregate. These aggregates are further linked by weak hydrogen bondings and strong π–π interactions to give rise to one-dimensional chelating double-chain supramolecular polymer. Cyclic voltammetry measurement reveals the oxidation and reduction process of the compound is irreversible in nature. Polymer 1 exhibits emission spectrum maximum at 548 nm under ultraviolet excitation. Antibacterial property measurement indicates that 1 has strong inhibition toward Staphylococcus aureus.
