AB  - A new tetraaza macrocycle bearing two xylyl spacers was synthesized as a potential binucleating ligand (L) and the crystal structure of its tetrachloride salt was determined by single crystal X-ray diffraction analysis. Corresponding Co(II) complexes were isolated as both mono- and dinuclear complexes of [Co(H2L)Cl-2]Cl-2, [Co2LBr2OH]Br and [Co2LI2OH]I, and characterized using different physico-chemical techniques. The single crystal X- ray diffraction technique for [Co(H2L)Cl-2]Cl-2 and [Co2LI2OH]I indicates that the Co ions adopt the geometry of a distorted tetrahedron in a tetracoordinated environment. The two metal centers in the [Co2LI2OH]I complex are bridged by a hydroxyl group with Co center dot center dot center dot Co distance of 3.501(1) angstrom. The bromo- and iodo-complexes show antiferromagnetic behavior which can be described by spin only Hamiltonian while spin- orbital coupling for tetrahedral coordinating cobalt ions is very small.
