摘要: The structure of heterospin complexes[M(DCA)2L2x]·yH2O, where M = Mn, Co, Ni, Cu, Lx is the nitronyl nitroxide radical; DCA dicyanamide anion, y 0, 1, or 2 studied. It found that nature of[M(DCA)2L2x]·yH2O characterized by formation multiple hydrogen bonds generating ribbons, layers, frameworks in crystals. analysis magnetostructural correlations means band calculations electronic confirms occurrence ferromagnetic exchange between unpaired electrons paramagnetic centers solid [Cu(DCA)2L21]·2H2O when distances copper ion and coordinated N-O group are short.
