Structural and Magnetic Studies of Polynuclear Transition Metal β‐Polyketonates

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.
