Synthesis, structure, catalytic and magnetic properties of a pyrazole based five coordinated di-nuclear cobalt(II) complex

A five coordinated dinuclear cobalt(II) complex, [Co2(L)2(N3)2] (1), displayed modest catalytic activity toward the oxidation of various allylic compounds. Low temperature magnetic studies gives high positive magnetic anisotropy (D = +29.8 cm−1) and a weak ferromagnetic exchange interaction (J = +10.3 cm−1).83
