LITHIUM CARBOXYLATE COORDINATION POLYMERS BASED ON TRIMESIC ACID
Three new metal-organic coordination polymers (H<sub>2</sub>NMe<sub>2</sub>)<sub>2</sub>[Li<sub>3</sub>(btc)(Hbtc)(DMF)<sub>4</sub>] (1), [Li<sub>5</sub>(DMF)<sub>6</sub>(btc)(Hbtc)]×2DMF (2), and [Li<sub>6</sub>(DMF)<sub>8</sub>(bdc)(Hbtc)] (3) (H<sub>3</sub>btc is trimesic acid, H<sub>2</sub>bdc is terephthalic acid) are prepared by heating LiOH with different aromatic carboxylic acids in dimethyl formamide (or its mixture with water). The crystal structures and composition of the compounds are determined by single crystal X-ray diffraction. Compound 1 has a layered structure; compounds 2 and 3 have a framework structure.
