Abstract
Control of covalent coordination polymer structures using non-covalent interactions is a promising way for obtaining functional materials by self-assembly in solution. Here we report the crucial role of halide anions in the formation of interpenetrating frameworks based on cyanometalate clusters. It was found that the interaction of [Re3Mo3Se8(CN)6]5- cluster anions and Cd2+ cations in aqueous ammonia led to the formation of the 1D polymeric compound {[Cd(NH3)5]2[Cd(NH3)4]3[Re3Mo3Se8(CN)6]2}·5H2O (1). Compound 1 is unstable outside the mother liquor due to the rapid loss of NH3 and H2O molecules. Addition of KX (X = Cl, Br, I) to the reaction mixture led to selective formation of 3D framework compounds {[Cd(NH3)4]3[Re3Mo3Se8(CN)6]}X (2-4 for X = Cl, Br, I, respectively) stabilized by N-H⋯X hydrogen bonding. Compounds 2-4 demonstrate high thermal stability as well as reversible loss of ammonia and reversible oxidation in the solid state.
