摘要: Two novel binuclear Mn(III) [C 22 H 26 Cl 4 Mn 2 N O 6 ] ( 1 ) and Cu(II) 14 Cu Schiff base complexes have been synthesized their crystal structures determined by single X-ray diffraction analysis. Structural analysis of shows that the ligand dimers coordinates toward one metal atom in a tridentate mode each is six-coordinated while four-coordinated. The two halves are related crystallographic inversion center. intramolecular non-bonding Mn⋯Mn separation 2.994 A for complex Cu⋯Cu ). Magnetic susceptibilities solid state measured over temperature range 2–350 K as function magnetic parameters with fitting procedure. measurements on reveal presence antiferromagnetic spin–exchange interactions between transition ions.
