N2 - 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 (χm) vs. temperature measurements. The χmTvs. T plots reveal that compounds 1, 2 and 3 are ferromagnetically coupled.
