Synthesis, crystal structures and magnetic properties of two three-dimensional heterotrimetallic compounds [Cu(en)2Li(H2O)][Fe(CN)6] and [Cu(en)2Li(H2O)][Co(CN)6] (en = ethylenediamine)
摘要:
Two heterotrimetallic compounds, [Cu(en)(2)Li(H2O)][Fe(CN)(6)] and [Cu(en)(2)Li(H2O)][Co(CN)(6)] (en = ethylenediamine), were synthesized and characterized. They are isostructural and crystallize in the orthorhombic space group Pbca at 293 K. The structures of the two compounds are composed of one-dimensional zigzag Fe/Co-C N-Cu chains linked by Li(I) ions into three-dimensional frameworks. Magnetic study of [Cu(en)(2)Li(H2O)][Fe(CN)(6)] reveals a weak magnetic interaction in the compound. (C) 2010 Elsevier B.V. All rights reserved.
