AbstractCoordination compounds of cobalt (II) with four new schiff bases of furyl glyoxal, 2‐furyl‐methyl‐2′‐carboxylato ketoanil (2 FMCKA), 2‐furyl glyoxal ethyenediimine (2 FGED), 2‐furyl giyoxal‐2′‐sulphonic acid anil (2 FGSAA) and 2‐furyl glyoxal‐2′‐chloro‐4‐nitro anilimimine (2 FGCNA) were prepared and characterised with the help of elemental analyses, magnetic measurements, infra‐red and electonic spectral data. Various ligand field parameters such as 10Dq, B&C,F2&F4,f2&f4,h,B°etc.and transition energies ν1;, ν2&ν3, were calculated with the help of electronic spectral data. The ν(C=N) bands in the IR spectra of all the ligands are lowered in complexation indicating nitrogen coordination of the ligands. All these studies indicate that cobalt(II) ion is
