Lithium carboxylate coordination polymers based on trimesic acid

Resumo

Three new metal-organic coordination polymers (H₂NMe₂)₂[Li₃(btc)(Hbtc)(DMF)₄] (1), [Li₅(DMF)₆(btc)(Hbtc)]·2DMF (2), and [Li₆(DMF)₈(bdc)(Hbtc)] (3) (H₃btc is trimesic acid, H₂bdc 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.
