| Recently, it has been found that the multinucleate complexes play an important role in organism due to their unique catalysis and biological activity. In addition, the function material significance of the multinucleate complexes is being discovered. Therefore, the synthesis and structure characterization about these complexes have attracted much attention in science field.In this dissertation, six novel multinucleate complexes were synthesized by using transition metal ions as spin carries,α,β- unsaturated Carboxylate and cyanide as bridging ligands. The products as-synthesized were characterized by element analyses, IR, UV. With X-ray crystallographic methods, the characterization results of products show that two complexes Cu2[CH2=CHCOO]4(C8H9NO)2 and Cr2(H2O)8(CH2=C(CH3)COO)2Cl4 are 1D chains by hydrogen bonds, two complexes K[Cu(en)2][Cr(CN)6] and K2[Ni(en)2][Fe(CN)6] are one-dimensional chains, and two complexes [Cu(L1)]3[Cr(CN)6]2 and[Cu(L2)]3[Cr(CN)6]2 are 2D stair-like layer. The compound of Cr2(H2O)8(CH2=C(CH3)COO)2Cl4 is Monoclinic Crystal system and P21/c space group with a=1.5327(7)nm, b=0.9989(5)nm, c=1.6130(3)nm,β=114.98°, the compound of K2[Ni(en)2][Fe(CN)6] is Monoclinic Crystal system and C2/c space group with a=1.7010(7)nm, b=0.8061(4)nm, c=1.4430(5)nm,β=109°, the compound of [Cu(L1)]3[Cr(CN)6]2 is Trigonal Crystal system and P3 space group with a=1.4895(2)nm, b=1.4895(2)nm, c=0.9774 (5)nm, and the compound of [Cu(L2)]3[Cr(CN)6]2 is Triclinic Crystal system and P1 space group with a=0..9251(6)nm, b=1.6405(3)nm, c=1.7801(4)nm,α=113°,β=94°,γ=102°, Z=2.
