[C 4 mim][Tb(hfacac) 4 ] ( 1 ) and [C 4 mpyr][Tb(hfacac) 4 ] ( 2 ) (C 4 mim = 1‐butyl‐3‐methylimidazolium, C 4 mpyr = N ‐butyl‐ N ‐methylpyrrolidinium) were obtained by reacting [C 4 mim]Cl (for 1 ) or [C 4 mpyr]Br (for 2 ) with (hexafluoroacetyl)acetone and terbium(III) chloride in a basic ethanol/water solution. Single‐crystal X‐ray structure analysis reveals Tb III to be chelated by four (hexafluoroacetyl)acetonate anions. Differential scanning calorimeter (DSC) investigations show both compounds to melt below 120 °C. For [C 4 mpyr][Tb(hfacac) 4 ] ( 2 ) the DSC traces indicate an organic plastic crystal behavior (OPCB). Both compounds show very strong emission in the visible region of light which are characteristic for the terbium(III) ion.(© Wiley‐VCH Verlag GmbH & Co. KGaA, 69451 Weinheim, Germany, 2009)
