The bimetallic complex of Ni2Co(TTHA).12H2O (TTHA=triethylene tetraminehexaacetic acid)was synthesized and characterized structurally and magnetically. The title complex crystallizes in the triclinic c=1.5041(4) nm;α=73.38(2),β=83.97(2),7=70.50(2)°.The crystal structure is built up of [Niz(TTHA)(H2O)2]2,,Co(H2O)6 2+and water molecules. The variable magnetic measurement shows that there is strong antiferromagnetic interaction between two Ni(Ⅱ) ions in [Ni2(TTHA)(H2O)2]2,with JNi,Ni=,141.64 cm,1,gNi=2.21 and that the constant of spin,orbit coupling of Co(Ⅱ) ion is ,134.8 cm,1.
