At room temperature,the copper(Ⅰ) complex [(PPh 3) 2Cu(C 7H 4NO 4)](C 7H 4NO 4=2,3 dicarboxylic acid pyridine)was obtained by treating [(PPh 3) 2Cu(BH 4)] with 2,3 dicarboxylic acid pyridine in the mixed solvent of e...At room temperature,the copper(Ⅰ) complex [(PPh 3) 2Cu(C 7H 4NO 4)](C 7H 4NO 4=2,3 dicarboxylic acid pyridine)was obtained by treating [(PPh 3) 2Cu(BH 4)] with 2,3 dicarboxylic acid pyridine in the mixed solvent of ethanol and dichloromethane.This complex was further characterized by physicochemical and spectroscopic methods.The structure of this complex was also determined by X ray structure analysis.The crystal is triclinic,space group P 1 with parameters a=11 130(2)?,b=12 960(3)?,c=13 420(3)?;α=79 38(3)°,β=75 55(3)°,γ=80 36(3)°,V=1827 4(6)? 3,Z=2,F(000)=780,D calc. =1 371g/cm 3,R=0 0371,and R w=0 1204.The results show that PPh 3 coordinates as monodentate ligand to the Cu(Ⅰ) atoms,and 2,3 dicarboxylic acid pyridine behaves as a bidentate ligand in the prepared complex.Hence,each copper atom had a CuP 2NO tetrahedron coordination skeleton.展开更多

The complex crystallizes in triclinic system, P1 space group with the cell parameters of a=1.004 2(2) nm, b=1.631 7(3) nm, c=1.887 7(4) nm, α=81.54(2)°, β=77.44(2)°, γ=79.39(2)°, V= 2.948 9(11) nm3, Z=4, and Dc=1.230 g·cm-3, the final R1=0.075 2, wR2=0.139 1. The complex crystallizes with two molecules in the asymmetric unit. Each Cu(Ⅰ) ion is coordinated by four N atom from the Vpy ligands and one O atoms from the nitrate anion, resulted in a square pyramidal geometry. The electrochemical studies reveal that redox of Cu2+/Cu+ in the complex is a quasi-reversible process. CCDC: 736638.展开更多
