AbstractA new end-on bis(μ-azido) nickel(II) complex of the formula [Ni2(L1)(N3)4] (1) (L1 = hexadentate Schiff base ligand made from the reaction of 2 moles of 2-benzoyl pyridine and 1 mole of triethylenetetramine) has been prepared and characterized by single crystal X-ray diffraction studies. Each nickel center is coordinated in a distorted octahedral (NiN6) fashion consisting of three nitrogen atoms from the hexadentate ligand moiety, two nitrogen atoms from two end-on azido ligands and the last one from another terminal azido ion. The variable temperature magnetic susceptibility of compound 1 shows that the nickel centers are ferromagnetically coupled. The Ni-N-Ni bridge angles are very similar [98.36(8)° and 97.66(9)°] and the Ni···Ni separation is 3.155(1) Å. The magnetic exchange coupling constant J = 21.8 cm-1 is consistent with the structure and the value has been compared with some similar reported compounds. © 2002 Elsevier Science Ltd.
