A novel heterodinuclear complex formed by the reaction of silver nitrate with Schiff base complex of copper(II) has been synthesized and characterized by Infrared (IR), ultraviolet-visible (UV-VIS), electron paramagnetic resonance (EPR) and X-ray diffraction methods. Preparation and crystal structure of the heterodinuclear complex, LCuAgNO3, (L = N,N'-ethylenebis(3-methoxysalicylideneimine) are reported. The crystal structure consists of ordered dinuclear units with Cu-II and Ag-I ions are bridged by two oxygen atoms of Schiff base ligand. The copper(II) ion has a distorted square-planar geometry involving the N2O2 donor set of Schiff base ligand. The g-values were calculated for title complex both in polycrystalline state at 298 K and in frozen DMF (113 K). The evaluated metal-ligand bonding parameters showed strong inplane sigma bonding.
