C26H40N4O7, Mr = 520.6, tetragonal, P4(3)2(1)2, a = 10.433 (1), c = 54.476 (7) A, V = 5930 (1) A3, Z = 8, Dm = 1.155 (3), Dx = 1.166 Mg m-3, lambda (Cu K alpha) = 1.54178 A, mu = 0.665 mm-1, F(000) = 2240, T = 295 K, R = 0.057 for 2037 observed reflections. The tetrapeptide adopts a type II beta-turn conformation with an extremely weak 4----1 intramolecular hydrogen bond [3.479 (7) A]. The molecules are held together in the crystal by three kinds of N-H---O intermolecular hydrogen bonds. |
