Copper, cobalt and nickel complexes with nitrogen donor ligands and trithiocyanurate dianion (ttcH2m) have been prepared and characterized by elemental analysis, electronic and EPR (copper complexes) spectra, and magnetic susceptibility measurements over the temperature range 78-291 K. Some of the complexes have also been studied by thermal analysis and by cycle voltammetry. Structures of the complexes have been proposed on the basis of magnetic and spectral properties. Two copper complexes of compositions Cu(bpy)(ttcH) and Cu(phen)(ttcH), where bpy = 2,2'-bipyridine, phen = 1,10-phenanthroline, are probably polymeric, whereas the copper complex with N,N'-bis(3-aminopropyl)ethylenediamine (bapen) of composition [Cu(bapen)ttcH)]-2H2O is mononuclear. We assume distorted octahedral structures for nickel complexes. A single crystal X-ray analysis of [Ni(bappn)(ttcH)]-5H2O shows that the central nickel atom is coordinated by tetradentate nitrogen ligand N,N'-bis(3-aminopropyl)-1,3-propanediamine and coordination is completed by sulfur and nitrogen atoms of trithiocyanurate dianion.
