Abstract: The title complex Cu( py)N (Vp=4-vinlpyridine)has been syn hesized and structurally characterized
by X-ray single crystal diffractometry. The complex crystallizes in triclinic system, P1 space group with the
cell parameters of a=1.042(2)nm,b=1.6317(3)nm,c=1.8877(4)nm,a=81.54(2),B=74(2),y=79.39(2)°,V=
2.9489(1)m =4, and =1.230 gcm the final R:=0. 075 2, WR=0.139 1. The complex crystallizes with two
nolecules 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 eometry. The electrochemical studies reveal that redox
of Cu/Cu*in the complex is a quasi-reversible process. CCDC: 736638
