摘要: Abstract The mononuclear CuII derivative, [Cu(L)(H2O)2] (1) [where H2L = N,N′-bis(3-methoxysalicylidenimino)-1,3-diaminopropane] is afforded and systematically characterized. In 1, the central atom linked to NNOO donor atoms of di-compartmental Schiff base precursor additionally coordinated with two water molecules; thus achieves a distorted octahedral geometry. EPR spectrum simulated WinEPR software having g|| = 2.210 g⊥ = 2.041. We also conduct DFT computational study which fits well experimental affirmation. room temperature magnetic susceptibility complex 1 confirms effective moment (μeff) value as 1.99 B.M. electrochemical measurement using cyclic voltammetry showed redox potentials at +0.63, −1.25, −1.82 V versus Ag/AgCl, are due reversible rapid Cu(III/II), Cu(II/I) Cu(I/0) process.
