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
