A symmetrical azomethine ligand L was synthesised from a reaction of m-phenylenediamine and o-vanillin in 1:2 molar ratio. Dinuclear complexes of Zn₂L₂ and Co₂L₂ have been successfully isolated and characterised through ¹H NMR, IR and magnetic moment. The x-ray crystal structure of Zn₂L₂ showed that the two Zn(II) nuclei were coordinated to two L moieties through the phenolic oxygen and imine nitrogen atoms, forming a slightly distorted tetrahedral geometry around the Zn(II) centres. When coordinated to metal centres, the signature n(C=N) of Lat 1616 cm^-1 experienced a shift towards lower wave numbers of 1573-1613 cm^-1. The Zn(II) complex was diamagnetic whereas the Co₂L₂ complex was paramagnetic with 3 unpaired electrons having µ _eff = 4.07 B.M. An antibacterial screening against methicillin resistant Staphylococcus aureus (MRSA) revealed that the activity of the complexes was more pronounced than that of the uncoordinated L. The complex Zn₂L₂ revealed the lowest MIC value of 0.56 µg/µl MIC, indicating that it was a better bactericides than Co₂L₂ and L, in that order.
