N-Methyl-l-leucyl-l-leucine hydro-chloride monohydrate.

ABSTRACT: In the title compound C(13)H(27)N(2)O(3) (+)·Cl(-)·H(2)O, obtained by deprotecting the amino and carboxyl groups of an inter-mediate in the synthesis of the cyclic penta-peptide Galaxamide, a number of hydrogen-bonding inter-actions occur including aminium N-H?Cl, amide-carboxyl N-H?O, water O-H?Cl and carbox-yl-water O-H?O associations. The aminium N-H?Cl?H-N bridging extensions give rise to zigzag chains extending along the a axis, the overall two-dimensional structure lying in the (110) plane.

In the title compound C(13)H(27)N(2)O(3) (+)·Cl(-)·H(2)O, obtained by deprotecting the amino and carboxyl groups of an inter-mediate in the synthesis of the cyclic penta-peptide Galaxamide, a number of hydrogen-bonding inter-actions occur including aminium N-H⋯Cl, amide-carboxyl N-H⋯O, water O-H⋯Cl and carbox-yl-water O-H⋯O associations. The aminium N-H⋯Cl⋯H-N bridging extensions give rise to zigzag chains extending along the a axis, the overall two-dimensional structure lying in the (110) plane ...[more]

l-Alanine methyl ester hydro-chloride monohydrate.

Project description:The enanti-opure title compound, C(4)H(10)NO(2) (+)·Cl(-)·H(2)O, forms a two-dimensional network by inter-molecular hydrogen bonding parallel to (010). Non-merohedral twinning with a twofold rotation about the reciprocal c* axis as twin operation was taken into account during intensity integration and structure refinement. This twinning leads to alternative orientations of the stacked hydrogen-bonded layers.

H-d-Phe-d-Pro-Gly methyl ester hydro-chloride monohydrate.

Project description:The conformation of the title tripeptide methyl ester hydro-chloride monohydrate, 1-[2-(methoxycarbonylmethylaminocarbonyl)pyrrolidin-1-ylcarbonyl]-2-phenylethanaminium chloride monohydrate, C(17)H(24)N(3)O(4) (+)·Cl(-)·H(2)O, is extended, but the structure cannot be classified as any typical secondary structure. Interactions through water molecules and chloride ions were formed, in addition to peptide-peptide hydrogen bonds, stabilizing the molecular packing. In comparison with the previous β-turn structure of the Phe-d-Pro-Gly analogue [Doi, Ichimiya & Asano (2007 ▶). Acta Cryst. E63, o4691], it was suggested that the difference between the chiralities of Phe and Pro residues of the title compound is important to induce the β-turn structure.

3-Chloro-2-methyl-anilinium chloride monohydrate.

Project description:In the title hydrated salt, C7H9ClN(+)·Cl(-)·H2O, the organic cations, anions and water mol-ecules are connected by N-H?Cl, N-H?O and O-H?Cl hydrogen bonds. These inter-actions lead to the formation of layers parallel to the ac plane.

Project description:In the title compound, C(13)H(15)N(2) (+)·Cl(-)·H(2)O, the ions and water mol-ecules are -connected by N-H⋯Cl, O-H⋯Cl, NH⋯Cl⋯HO, NH⋯Cl⋯HN and OH⋯Cl⋯HO inter-actions, forming discrete D(2) and D(2) (1)(3) chains, C(2) (1)(6) chains and R(4) (2)(8) rings, leading to a neutral two-dimensional network. The crystal structure is further stabilized by π-π stacking inter-actions [centroid-centroid distance = 3.652 (11) Å].

Glycine methyl ester hydro-chloride.

Project description:THE TITLE COMPOUND [SYSTEMATIC NAME: (methoxy-carbonyl-meth-yl)ammonium chloride], crystallizes as a salt, C(3)H(8)NO(2) (+)·Cl(-), with the charged species inter-acting mutually via strong and highly directional N(+)-H?Cl(-) hydrogen bonds which lead to the formation of a supra-molecular tape running parallel to the c axis. Tapes close pack in the solid state mediated by multipoint recognition synthons based on weak C-H?O inter-actions and van der Waals contacts between adjacent methyl groups.

4-Hy-droxy-1,2,6-tri-methyl-pyridinium chloride monohydrate.

Project description:In the crystal of the title hydrated mol-ecular salt, C8H12NO(+)·Cl(-)·H2O, the water mol-ecule makes two O-H⋯Cl hydrogen bonds, generating [010] zigzag chains of alternating water mol-ecules and chloride ions. The cation is bonded to the chain by an O-H⋯O hydrogen bond and two weak C-H⋯Cl inter-actions. Weak aromatic π-π stacking [centroid-centroid separation = 3.5175 (15) Å] occurs between the chains.
