摘　　要：A detailed synthesis is described for binuclear cage ternary complexes Cu₂A₄ [（NH₂）₂CO]₂, where A = CH₂ =CH—COO^- and CH₂ =C（CH₃）—COO^-. Elemental analysis and thermal analysis have been investigated. The molecular structure of Cu₂ （CH₂ = CH—COO）₄[（NH₂）₂CO]₂ was determined by single crystal X-ray diffraction. The material forms blue crystal with tetragronal symmetry, space group P4₂/n, a = b = 1. 239 35（6） nm, c = 1. 398 05 （16） nm, Z = 4. There exists, a magnetic exchange interaction between the two paramagnetic Cu atoms. The Cu—Cu bond length is 0.260 94 nm.A detailed synthesis is described for binuclear cage ternary complexes Cu2A4 [(NH2)2CO]2, where A = CH2 =CH-COO and CH2 =C(CH3)-COO- .
