Abstract

Gas-sorption properties of Cobalt (II)-Carborane-based coordination polymers as a function of morphology are discussed. Compound 1 and Cobalt (II) salts were used successfully to synthesize three new coordination-polymer materials simply by varying the reaction solvent and temperature conditions. The coordination modes of the p-CDC ligand generate two distinct structural motifs, namely four- and eight-membered rings, which reciprocally organize to yield two, interpenetrated, polymeric networks. SEM images of the as-synthesized substances reveal distinct differences in morphology. All three materials retain their apparent morphology upon thermally induced solvent desorption. The hydrogen-uptake properties of all the materials also measured, following treatment with heat and vacuum. After 12-hour, the agglomerates were collected by centrifugation and washed twice with methanol. The washed particles were dried under vacuum at room temperature to afford as a pink powder.
