Abstract

Tridentate Schiff base ligands L¹ and L², derived from the condensation of 2-hydroxy-3-methox-ybenzaldehyde (L) with 2-aminoethanol or 2-aminobutan-1-ol, react with nickel chloride, azide, or thiocyanate to give rise to two dinuclear complexes of formulas [Ni ₂(L)-(L¹)2N₃]-H₂O (1), [Ni ₂(L²)₃(μ₁,1-N₃)]- 2H₂O (2), and one tretranuclear complex [Ni₂(L ²)₂(NCS)]₂(C2H₅OH)₂ (3), where L¹ - HOCH₂CH(C₂H₅)NCHC ₆H₃(O^-)(OCH₃) and L² - HO(CH₂)₂NCHC6H3(O^-)(OCH₃). We have characterized these complexes by analytical, crystal structures, and variable temperature magnetic susceptibility measurements. The magnetic properties of the complexes are studied by magnetic susceptibility (χ_m) vs. temperature measurements. The χ_mT_vs. T plots reveal that compounds 1, 2 and 3 are ferromagnetically coupled.
