%X 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.
