Tetranuclear nickel(II) complex with tripodal hydroxyl ligand functionalized by additional salicylaldehyde donor pendant: Synthesis, crystal structure and magnetic property

The tetranuclear cubane-like [Ni4(H3hbhpd)4] · 4H2O complex has been prepared by the reaction of nickel(II) acetate with H5hbhpd, where H5hbhpd is 2(2-hydroxy-benzylamino)-2-hydroxymethyl-propane-1,3-diol. The X-ray diffraction analysis of the complex showed a Ni4O4 cubane arrangement of four nickel atoms. Magnetic studies indicate ferromagnetic behavior for the complex. The magnetic data were fitted and the parameters are given as g = 2.21, J1 = 0.32, J2 = 8.27, D = −0.05 cm−1.
