Abstract (EN): An unprecedented series of Mn2+-based metal-organic framework (MOF) materials prepared and isolated in ionic liquids (ILs) is reported. Ionothermal reactions of Mn(OAc)(2) with H(3)btc (benzene-1,3,5-tricarboxylic acid) in two groups of [rmi]X (rmi = 1-alkyl-3-methylimidazolium; r = ethyl or propyl, X = Cl, Br, or I) ILs produced three slightly different 3D MOFs formulated as [rmi][Mn(btc)] [r = ethyl (1), propyl (2), and (3)], whose architectures can be envisaged as (3,6)connected pyr topological nets. Compounds 1-3 are the preferred products when the metal center is half filled d-shelled Mn with the cations of ILs being [emi](+) or [pmi](+). The comparison of the ionothermal synthesized M-btc systems suggests a significant combinatorial influence of metal-direction and ILs' cationic template, contrasting with subtle effect of ILs' halides on the MOF structures.
