Аннотация

A co-crystal of L-alanyl-L-valine (AV) and L-alanine (A), AV⋅A⋅(H2O), has been prepared and characterized by single crystal XRD analysis. Crystal data: C11H25N3O6; M = 295.3; orthorhombic, space group P2(1)2(1)2(1); a = 16.4773(17), b = 18.3932(19), c = 5.0398(5) Е, V = 1527.4(3) Е3, Z = 4; dcalc = 1.284 g/cm3. Experimental parameters: T = 100 K; diffractometer, radiation: Kappa APEX II, graphite-monochromatized MoKα; R1 = 0.046,
wR2 = 0.120 for 4639 unique reflections and 214 refinement parameters. The L-alanyl-L-valine dipeptide molecules assemble to form a parallel β-sheet through hydrogen bonds, while the L-alanine molecules fill the large channels located in the interlayer space. AV⋅A⋅(H2O) is the first layered structure based on a representative of hydrophobic dipeptides that form hexagonal tubular structures in the solid state, as well as the first inclusion compound of AV with a chiral guest.
