RETRACTED: Synthesis, characterization and crystal structure of a CuSCN complex containing a new bidentate N,N′-bis(2-nitrocinnamaldehyde)ethylenediamine Schiff base and triphenylphosphine (Retracted Article)

Reaction of copper(I) thiocyanate (CuSCN) and triphenylphosphine (PPh3) with a new bidentate Schiff base, N,N'-bis(2-nitrocinnamaldehyde)ethylenediamine (Nca(2)en), in a 1 : 1 mol ratio in acetonitrile resulted in the formation of a complex formulated as [CuSCN(Nca(2)en)(PPh3)]. The ligand (Nca(2)en) and complex were characterized by analyses, IR, electronic, H-1 NMR spectroscopy, and X-ray diffraction. The Nca(2)en is roughly planar and displays a trans configuration with respect to the C=N double bond. Nca(2)en acts as a bidentate ligand coordinating via two N atoms to copper and adopts a trans, trans configuration in this complex. The SCN ligand is coordinated through sulfur. The ligand and its copper(I) complex crystallize in the monoclinic space group. The geometry around the copper atom is distorted tetrahedral with N(3)-Cu-N(2), 81.59(11) and P-Cu-S, 117.29(9).
