Two ternary complexes Cu2A4[OP(OCH3)3]2 (A represents CH2=CH-COO- and CH2=C(CH3)-COO-) have been synthesized, and elemental analyses, IR, ESR, electronic reflectance spectra and magnetic studies were carried out. The single crystal X-ray diffraction shows that Cu2[CH2=C(CH3)-COO]4[OP(OCH3)3]2 is triclinic, with space group P1, a = 1.05128(13), b = 1.7559(5), c = 1.94479(3) nm, α =91.263(14)°,(β = 102.559(6)°,γ= 106.339(13)°, Z = 4 and R = 0.0668. Two copper(Ⅱ) atoms are bridged by four (a-methacrylate groups, and each copper(Ⅱ) atom is coordinated with a trimethyl phosphate molecule in the axial position, forming a distorted square pyramidal configuration. The symmetric center is between the two copper(Ⅱ) atoms, and the Cu-Cu bond distance is 0.26098(6) nm. The Cu-Cu distance and magnetic studies suggest that there exist anti-ferromagnetic interactions between the two copper(Ⅱ) atoms.

The single crystal X-ray diffraction analysis of the Cu2 [CH2 = C (CH3) -COO] 4 [OP (OCH3) 3] 2 is triclinic with space group P1, a = 1.05128 (13) 1.7559 (5), c = 1.94479 (3) nm, α = 91.263 (14) °, β = 102.559 (6) °, γ = 106.339 (13) °, Z = 4 and R = ) atoms are bridged by four (a-methacrylate groups, and each copper (II) atom is coordinated with a trimethyl phosphate molecule in the axial position, forming a distorted square pyramidal configuration. The symmetric center is between the two copper (II) atoms , and the Cu-Cu bond distance is 0.26098 (6) nm. The Cu-Cu distance and magnetic studies suggest that there exists anti-ferromagnetic interactions between the two copper (II) atoms.
