Ni(II), Cu(II), Zn(II) and Cd(II) complexes of an N4-donor Schiff base, containing (CH2)2 as spacer, have been prepared. The X-ray crystal structures of monohelical Ni(ETs)·H 2O and the homochirally crystallised Δ-Cu(ETs), as well as the meso-helicate Zn2(ETs)2·MeCN [H2ETs: N,N′-bis(2-tosylaminobenzylidene)-1,2-diaminoethane] have been solved. In the latter, the ligand behaves as bis-bidentate, displaying a C -type arrangement, instead of the typical S -type fashion present in bis-helical dinuclear complexes.
