The First Mixed-Valence Co~(II)Co~(III) One-dimensional Chain Coordination Polymer: Synthesis and Structre fo [Co_(2~(II))Co~(III)(nta)_2(azpy)_4(H_2O)_6] centre dot [Co~(II)Co~(III)(nta)_2(axpy)_2(H_2O)_2] centre dot 4H_2O

摘要

A novel mixed-valence Co~(II)Co~(III) complex [Co_(2~(II))Co~(III)(nta)_2(azpy)_4(H_2O)_6] centre dot[Co~(II)Co~(III)(nta)_2(azpy)_2(H_2O)_2] centre dot 4H_2O was synthesized and characterized.Its structure is composed of new motifs,called "the rod with open sidearms" anion and H-like trinuclear cation,which interlock each other.The stack of onedimensional chains of [Co~(II)Co~(III)(nta)_2(azpy)_2(H_2O)_2] forms two-dimensional rhombus pores through #pi#-#pi# stacking interaction of pyridyl rings from azpy.
