A 3D metal-organic framework, namely, {[EMIM][In-3(mu(3)-OH)(2)(1,2,4,5-BTC)(2)center dot 2H(2)O]}(n) (1) (1,2,4,5-BTC= 1,2,4,5-benzenetetracarboxylate), was synthesized by using 1-ethyl-3- methylimidazolium bromide ([EMIM] Br) ionic liquid as solvent. The 7-coordinated pentagonal bipyramidal In(1) and octahedral In(2) atoms are connected by the mu(3)-OH groups to form an infinite [In-3(mu(3)-OH)(2)](n) inorganic chain along the a-axis, which are further extended by 1,2,4,5-BTC ligands to generate the 3D anionic microporous framework of 1. The [EMIM](+) cations occupy the D channels acting as template and charge-balancing species. Compound 1 shows strong blue luminescence and remarkable photocatalytic degradation of methylthionine chloride.
