Abstract
A europium(III) coordination compound based on thiopheneacrylic acid (Htpa), triaquatris[3-(thiophen-2-yl)prop-2-enoato-κ2
O,O′]europium(III)–3-(thiophen-2-yl)prop-2-enoic acid (1/3), [Eu(C7H5O2S)3(H2O)3]·3C7H6O2S or [Eu(tpa)3(H2O)3]·3(Htpa) (1), where tpa is the conjugate base of Htpa, has been synthesized and structurally characterized. Compound 1 crystallizes in the trigonal space group R3. The structure of 1 consists of a discrete molecular complex [Eu(tpa)3(H2O)3] species and the Htpa molecule. In the crystal, the two components are involved in O—H...O [ring motif R

2(8)] and C—H...π hydrogen-bonding interactions. These interactions were further investigated by Hirshfeld surface analysis, which showed high contributions of H...H, H...C/C...H and H...O/O...H contacts to the total Hirshfeld surfaces.
