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

The title compound, C(26)H(26)N(4)O(6)·2C(4)H(8)O, 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. [Image: see text]
