Copper(II) nitrate hemipentahydrate and cobalt(II) nitrate hexahydrate with the ligands 1,3-adamantanedicarboxylic acid and 4,4'-trimethylenedipyridine were used to synthesize a series of metal-organic frameworks (MOFs) with varying colors and structures. The various structures were formed by altering the solvent, template, and temperature. The compounds were characterized by infrared spectroscopy, thermogravimetric analysis, and x-ray crystallography. Our analysis of the data suggests that we have synthesized two novel MOFs: a purple copper MOF and a red cobalt MOF. The x-ray structures show that the copper MOF exhibits a one-dimensional structure containing 1,3-adamantanedicarboxylic acid and 4,4'-trimethylenedipyridine, while the cobalt MOF adopts a one-dimensional structure containing 1,3-adamantanedicarboxylic acid, 4,4'-trimethylenedipyridine, and methanol. Investigations on the formation of polymer composites with these MOFs are in progress.
