Investigation of Dipodal oxy-Schiff base and its salen and salophen Fe(III)/Cr(III)/Mn(III) Schiff bases (N sub(2)O sub(2)) caped complexes and their magnetic and thermal behaviors

Six new dinuclear Fe(III)/Cr(III)/Mn(III) complexes have been involved tetradentate (N sub(2)O sub(2)) Schiff bases (salenH sub(2)) and (salophenH sub(2)) with 2,4-bis(4-hydroxyphenylimino-4'-formylphenoxy)-6-methoxy-1,3 ,5-triazine have been synthesized. The complexes were characterized as high-spin (S = 5/2) distorted trigonal bipyramidal salen/salophenFe(III) bridged, distorted trigonal bipyramidal (S = 3/2) salen/salophenCr(III) and high-spin distorted trigonal bipyramidal (S = 2) salen/salophenMn(III) by OH super(-) groups. The structures of ligand and complexes were identified by using elemental analysis, thermal analysis, magnetic susceptibility, LC-MS, ICP-AES, super(1)H NMR and FT-IR spectral data.
