A series of mono- and dinuclear complexes of Ni(II) and Co(II) with two hexadentate ligands α,α'-bis(bis(2-(diphenylphosphino)ethyl)amino)ethane(BDPE) and α,α'-bis(bis(2-(diphenylphosphino)ethyl)-amino)-m-xylene (BDPX) were synthesized and chracterized by means of elemental analyses, molar conductance, magnetic susceptibilities, infrared, electronic and 31P NMR data. The molecular structure of a mononuclear Ni(II) complex, [Ni(BDPE)](CIO4)2.CH2Cl2, was established by single-crystal X-ray diffraction methods. Crystal data: C59H62NiCl4N2O8P4, M = 1250.98, orthorhombic, space group Pbca, V= 11834.3(7) Å3, Z= 8, a= 10.817(1), b = 31.683(7), c=34.538(1) Å, final R 0.055 (Rw = 0.057) for 3118 observed reflections. The Ni(II) ion exists in a slightly distorted square planar geometry, the coordination sites being two phosphorous and two tertiary nitrogen atoms of the ligand. Electrochemical studies of the complexes were also carried out. |
