18-Crown[6] has been used to prepare new organic–inorganic complexes with Cs2CO3 and aromatic mono-, di- and tricarboxylic acids (benzoic, isophthalic, terephthalic and trimesic acid). The complexes 18-crown[6]$Cs[trimH2] (1), 18-crown[6]$Cs[isoH] (2), 18-crown[6]$Cs2[isoH]2$2H2O (3), (18- crown[6])3$Cs3[trim]$9H2O (4), 18-crown[6]$Cs[ben]$H2O (5) and (18-crown[6])6$Cs4[tereH]2- [tere]$5H2O (6) have been characterized by single-crystal X-ray diffraction. The thermal behaviour of 1, 2 and 4 has been investigated by a combination of solid-state techniques including differential scanning calorimetry (DSC), thermogravimetric analysis (TGA) and variable temperature X-ray powder diffraction (VT-XRPD); in the case of 2 hot stage microscopy was used to clarify its thermal behaviour.
