Polyhedral Metal-Imidazolate Cages: Control of Self-Assembly and Cage to Cage Transformation

Xiao-Ping Zhou, Yuan Wu, and Dan Li*



Abstract: A series of neutral cubic nickel(II)- imidazolate Ni8L12X4 cages were prepared by rational choices of substituents and anions with solvothermal subcomponent self-assembly technology. Both substituents and halide anions play a critical role in the formation and stabilization of cubic cages. Changing one of the factors in the reaction will switch the final structure to a Ni14L24 rhombic dodecahedral cage. The cubic cage can transform to a large rhombic dodecahedral cage in the presence of methylamine at room temperature accompanied by a color change from purple to light yellow.
