Ionic Liquid as Solvent for the Synthesis and Crystallization of a Coordination Polymer:  (EMI)[Cd(BTC)] (EMI = 1-Ethyl-3-methylimidazolium, BTC = 1,3,5-Benzenetricarboxylate)

Abstract

An ionic liquid, 1-ethyl-3-methylimidazolium bromide, is used as reaction medium for the synthesis and crystallization of a coordination polymer, (EMI)[Cd(BTC)] (1) (EMI = 1-ethyl-3-methylimidazolium, BTC = 1,3,5-benzenetricarboxylate), which forms an anionic three-dimensional framework with 1-ethyl-3-methylimidazolium cations located in the void space.

Speciation of Rare‐Earth Metal Complexes in Ionic Liquids: A Multiple‐Technique Approach

“…[24][25][26][27][28][29][30] Additionally, ionic liquids are promising solvents for the crystallization and crystal engineering of metal complexes (coordination polymers) and they are able to trap unique coordination environments. [31][32][33][34][35][36][37][38] Besides these applications, ionic liquids have been reported to be interesting hosts for photochemical and spectroscopic studies and can be regarded as potential new optical materials.…”

We thank the FWO-Vlaanderen and the Netherlands Organization for Scientific Research (NWO) for providing beam time at the Dutch-Belgian Beamline (DUBBLE, BM26A, ESRF).…”

One‐Step Synthesis of MIL‐53(Al)/Boehmite Composites

“…In the latter case, the cation and anion of the IL serve as counter ion for a cationic framework or for an anionic framework, respectively, and remain in the structure. Furthermore ILs were used as micro/nano-emulsion of two non-miscible ILs [7] or in the system IL/CO 2 [8] [11] or the recently found [EMIm]Mn(btc) [12].…”

Ionothermal synthesis and crystal structure of a 2D metal organic framework: [emim]2[Cd2(btec)Br2] (emim=1-ethyl-3-methylimidazolium, btec=1,2,4,5-benzenetetracarboxylate)

“…Recently, ionothermal synthesis have shown high promise in the preparation of novel inorganic or organic-inorganic hybrid materials such as inorganic nanoparticles [11], zeolites and zeotype materials [12][13][14] and metal organic frameworks (MOFs) [15][16][17][18][19][20][21][22][23][24][25][26]. Under ionothermal conditions, ILs not only may serve as solvent [15,17], but also function as templates, charge compensating groups and/or coordination ligands with their cations [15,16,23,24] or anions [25,26] or both [18][19][20] present in the resulting structures. 2D-[Cu(1,3-bis(4-pyridyl)propane)]BF 4 [25] and 3D-[Cu 3 (tpt) 4 ](BF 4 ) 3 Á(tpt) 2/3 Á5H 2 O (tpt = 2,4,6-tris(4-pyridyl)-1,3,5-triazine] [26] represent the first two MOFs obtained ionothermally.…”
