Crystal to crystal transformation induced a novel Cu(ii)-MOF with zigzag ⋯I3−⋯I3−⋯ chains†
Abstract
A novel Cu(II)-MOF {[Cu4(TTTMB)4(NO3)4(H2O)5]·(NO3)2·(I3)2·H2O}n containing polyiodide I3− was obtained through crystal to crystal transformation by immersing a CdII complex {[Cd3(TTTMB)4I2]·I4}n in an aqueous solution of Cu(NO3)2. There are two kinds of I3− arranged as infinite zigzag ⋯I3−⋯I3− chains between the layers of the Cu(II)-MOF.
