Synthesis and Structural Studies on Homo‐and Heterobinuclear Complexes of Cu(II), Ni(II) and Co(II) with Arylideneanthranilic Acid Schiff Bases

Homo and heterobinuclear complexes of arylidene- anthranilic acids with Cu(II), Ni(II) and Co(II) are prepared and characterised by chemical analysis, spectral and X-ray diffraction techniques as well as conductivity measurements. Two types of homo-binuclear complexes are formed. The first has the formula M2L2Cl2(H2O)n where M=Cu(II), Ni(II) and Co(II), L = p-hydroxybenzylideneanthranilic acid (hba), p-dimethylaminobenzylideneanthranilic acid (daba) and p-nitrobenzylideneanthranilic acid(nba) and n = 0–3. The second type has the formula M2LCl3(H2O)n in which M is the same as in the first type, L = benzylideneanthranilic acid (ba), (daba) (in cases of Cu(II) and Ni(II)); and n = 1–5. Heterobinuclear complexes having the formula (MLCl2H2O) MCl2(H2O)n are isolated by reaction of Cu(II) binary chelates with Ni(II) and/or Co(II) chlorides. These are also characterized and their structures are elucidated.
