Syntheses, characterization, crystal structure and magnetic properties of copper(Ⅱ)α, β-unsaturated carboxylate complexes with trimethyl phosphate
摘    要:Two ternary complexes Cu2A4OP(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 Cu2CH2== C(CH3)—COO]4OP(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 antiferromagnetic interactions between the two copper(Ⅱ) atoms.
