N,N′-[1,4-Phenylenebis(iminocarbonyl)]bis(L-phenylalanine) tetrahydrofuran disolvate

Abstract

The title compound, C26H26N4O6·2C4H8O, representing a bis-urea with terminal phenylalanine units, crystallized with two tetrahydrofuran (THF) molecules. The main molecule is located on a crystallographic twofold axis, while the solvent molecule is disordered over two positions, with occupancies of 0.571 (15) and 0.429 (15). The host molecules are linked by N—H...O=C hydrogen bonds and C—H...O contacts with R 2 1(6) and R 2 1(7) ring motifs. The THF molecules enclosed in the crystal are connected to the bis-urea compound via O—H...O and C—H...O interactions.
