1D arrays of [Cu(Phca2en)2][AgI2] by fourfold phenyl embraces isolating diiodoargenate(I) anions

The reaction of N,N′-bis(β-phenyl-cinnamaldehyde)-1,2-diiminoethane (Phca2en) with a mixture of CuI and AgNO3 (molar ratio 1:2:1) yields the novel mononuclear [Cu(Phca2en)2][AgI2] complex. The crystal and molecular structure of [Cu(Phca2en)2][AgI2] was determined by X-ray crystallography from single-crystal data. The structure contains cationic moieties of copper(I) ion coordinated to four N atoms of two Phca2en ligands in a distorted tetrahedral fashion and isolated linear diiodoargenate(I) anions. The Phca2en ligand adopts a Z,Z configuration. A supramolecular motif that is a one-dimensional array has been identified from the crystal packing analysis.

The synthesis and structure of [Cu(Phca2en)2][AgI2], which forms a crystal supramolecular motif, is described. In this structure, the cations are maintained in a one-dimensional array by local interactions analogous to the 4PE while isolating a linear monomeric AgI2 anion.Figure optionsDownload as PowerPoint slide
