| Abstract: | Abstract Tridentate Schiff base ligands L1 and L2, derived from the condensation of 2-hydroxy-3-methoxybenzaldehyde (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 Ni2(L)(L1)2N3]·H2O (1), Ni2(L2)3(μ1,1-N3)]·2H2O (2), and one tretranuclear complex Ni2(L2)2(NCS)]2(C2H5OH)2 (3), where L1 = HOCH2CH(C2H5)NCHC6H3(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 χM
T vs. T plots reveal that compounds 1, 2 and 3 are ferromagnetically coupled. |
