Abstract:The title complex Cu(Vpy)NO3(Vpy=4-vinylpyridine)has been synthesized and structurally characterized
by X-ray single crystal diffractometry.The complex crystallizes in triclinic system,P1 space group with the
cell parameters ofa=1.0042(2) nm,b=1.631 7(3)nm,c=1.8877(4)nm,a=81.54(2)。,fl=77.44(2)。,y=79.39(2)。, :
2,948 9(11)nm ,Z=4,and D =1.230 g・cm习,tlae final R1=0.075 2,wR2=0.139 1.The complex crystallizes with two
molecules in the asymmetirc unit.Each Cu(I)ion is coordinated by four N atom from the Vpy ligands and one 0
atoms from the nitrate anion,resulted in a square pyramidal geometry.The electrochemical studies reveal that redox
0f Cu2+/Cu in the complex is a quasi—reversible process.CCDC:736638.
