Abstract
Preparations of eleven complexes of the open-chain, aromatic nitrogen/thioether donor, N 2S 3 and N 2S 4 ligands, L1 and L2, are described. The complexes have been characterized by using conductivity, cyclic voltammetry, magnetic susceptibility, ESR, NMR and UV–Vis spectroscopies where appropriate and by X-ray crystallography for [Co(L2)][ClO 4] 2. Crystal data: monoclinic, space group C2/c, a=18.177(3), b=11.600(2), c=14.552(2) Å, β=124.703(6)°, Z=4, R=0.039, R w=0.050. The presence of a spin-crossover system for the Co(II) complexes has been detected.
