摘要: Abstract The new tetranuclear cobalt(II) complex with formula [Co4(N3)8(4,5-diazafluoren-9-one)4] (1) is reported. Complex 1 a defective dicubane azide-bridged compound showing only azido bridging ligands in the μ1,1– and μ1,1,1– coordination modes. magnetic properties of are Magnetic susceptibility measurements indicate ferromagnetic coupling. data have been fitted to 2 K by considering two different superexchange coupling constants. out-of-phase signal χM″ displays frequency-dependence below approximately 9 K.
