Abstract

Two mononuclear complexes [Cu(NCS)(trenb)]ClO<sub>4</sub> (<strong>1</strong>) and [Co(NCS)(trenb)]Cl·H<sub>2</sub>O (<strong>2</strong>), where trenb is tris[2-(benzylamino)ethyl]amine, were prepared and characterized by elemental analysis, IR, electronic and EPR spectra. Their crystal structures were determined by X-ray diffraction. Complexes <strong>1</strong> and <strong>2</strong> are both five-coordinated with their metal centers in the distorted trigonal-bipyramidal environment. Each metal(II) ion coordinates with the tetradentate trenb, and one isothiocyanate anion. The two complexes are not isostructural as there are also a chloride and a water molecule in the asymmetric unit of <strong>2</strong>. Besides balancing the charge, the chlorides are also involved in intramolecular and intermolecular hydrogen bonds with the secondary amine groups, resulting in a one-dimensional chain structure. UV-VIS spectrum and EPR measurement for <strong>1</strong> have unambiguously confirmed that the five-coordinated structure is retained in solution, even in the donating solvent such as DMF. <p>
