Neutral Mn(II), Fe(II) and Co(II) complexes with an N-tosyl substituted N4-Schiff base containing a tetra-methylene spacer have been prepared. The X-ray crystal structures of ligand H2BTs [N,N′-bis(2-tosylaminobenzylidene)-1,4-diaminobutane] and helical Co(BTs)·0.5H2BTs have been solved. The Co(II) ion assumes a distorted tetrahedral coordination geometry, involving the four donor N-atoms of the dianionic ligand. Additionally, secondary interactions between the metal centre and one of the O-atoms of each tosyl group were detected. These groups are differently conformed, so that the ligand behaves as a non-symmetric helicand.
