Copper(I) complex [Cu(ca2dapte)(NCS)] with the flexible N _2S_2 Schiff-base tridentate ligand: Synthesis, characterization and crystal structure

摘要

New copper(I) complex involving the flexible N_2S_2 Schiff-base ligand ca_2dapte [Cu(ca_2dapte)(NCS)], [ca 2dapte = N,N'-bis-(cinnamaldehyde)-1,2-di(o-iminophenylthio) ethane], has been synthesized and structurally characterized by X-ray diffraction analysis. The coordination polyhedron around the Cu(I) center is best described as a distorted tetrahedron. The flexible N_2S_2 Schiff-base ligand ca2dapte acts as a tridentate ligand via two S atoms and one N atom, while the NCS- ligand is coordinated to the metal ion through its nitrogen atom.
