| Abstract: Two ternary complexes Cu 2A 4(C11 H12 N 2O)2[Ais CH2=CH-COO- and CH2=C(CH3) COO-, C11 H12 N2O=antipyrine] have been synthesized, accompanying elemental analyses, IR, ESR, electronic reflectance spectra and magnetic studies. The single crystal Xray diffraction shows that Cu2[CH2=C(CH3)-COO]4(C11 H12N2O)2 crystallizes in the monoclinic with space group P2 1/ n, a =1.20264(8) nm, b =0.87604(10)nm, c =1.88246(14) nm, β =100.802(5)°,Z=2 and R =0.0304. Two copperⅡ atoms are bridged by four α-methylacrylate groups, and each copperⅡ atom is coordinated with antipyrine molecule in 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 0.26615(3) nm. The Cu-Cu distance and magnetic studies suggest that there exist antiferromagnetic interaction between two copperⅡ atoms. |
