Crystal structure of (S)-2-amino-2-methyl-succinic acid.

ABSTRACT: The title compound, C5H9NO4, crystallized as a zwitterion. There is an intra-molecular N-H?O hydrogen bond involving the trans-succinic acid and the ammonium group, forming an S(6) ring motif. In the crystal, mol-ecules are linked by O-H?O hydrogen bonds, forming C(7) chains along the c-axis direction. The chains are linked by N-H?O and C-H?O hydrogen bonds, forming sheets parallel to the bc plane. Further N-H?O hydrogen bonds link the sheets to form a three-dimensional framework.

The title compound, C5H9NO4, crystallized as a zwitterion. There is an intra-molecular N-H⋯O hydrogen bond involving the trans-succinic acid and the ammonium group, forming an S(6) ring motif. In the crystal, mol-ecules are linked by O-H⋯O hydrogen bonds, forming C(7) chains along the c-axis direction. The chains are linked by N-H⋯O and C-H⋯O hydrogen bonds, forming sheets parallel to the bc plane. Further N-H⋯O hydrogen bonds link the sheets to form a three-dimensional framework. ...[more]

Crystal structure of 2-(methyl-amino)-tropone.

Project description:The title compound, 2-(methyl-amino)-cyclo-hepta-2,4,6-trien-1-one, C8H9NO, crystallizes in the monoclinic space group P21/c, with three independent mol-ecules in the asymmetric unit. The planarity of the mol-ecules is indicated by planes fitted through the seven ring carbon atoms. Small deviations from the planes, with an extremal r.m.s. deviation of 0.0345 Å, are present. In complexes of transition metals with similar ligands, the large planar seven-membered aromatic rings have shown to improve the stability of the complex. Two types of hydrogen-bonding inter-actions, C-H⋯O and N-H⋯O, are observed, as well as bifurcation of these inter-actions. The N-H⋯O inter-actions link mol-ecules to form infinite chains. The packing of mol-ecules in the unit cell shows a pattern of overlapping aromatic rings, forming column-like formations. π-π inter-actions are observed between the overlapping aromatic rings at 3.4462 (19) Å from each other.

Crystal structure of the bis-(cyclo-hexyl-ammonium) succinate succinic acid salt adduct.

Project description:The crystal structure of the title salt adduct, 2C6H14N(+)·C4H4O4 (2-)·C4H6O4, consists of two cyclo-hexyl-ammonium cations, one succcinate dianion and one neutral succinic acid mol-ecule. Succinate dianions and succinic acid mol-ecules are self-assembled head-to-tail through O-H⋯O hydrogen bonds and adopt a syn-syn configuration, leading to a strand-like arrangement along [101]. The cyclo-hexyl-ammonium cations have a chair conformation and act as multidentate hydrogen-bond donors linking adjacent strands through inter-molecular N-H⋯O inter-actions to both the succinate and the succinic acid components. This results in two-dimensional supra-molecular layered structures lying parallel to (010).

Crystal structure of 4-(di-methyl-amino)-pyridinium 4-amino-benzoate dihydrate.

Project description:In the title hydrated mol-ecular salt, C7H11N2 (+)·C7H6NO2 (-)·2H2O, the cation is protonated at the pyridine N atom and the dihedral angle between the benzene ring and the CO2 (-) group in the anion is 8.5 (2)°. In the crystal, the cation forms an N-H⋯O hydrogen bond to the anion and the anion forms two N-H⋯O hydrogen bonds to adjacent water mol-ecules. Both water mol-ecules form two O-H⋯O hydrogen bonds to carboxyl-ate O atoms. In combination, these hydrogen bonds generate a three-dimensional network and two weak C-H⋯π inter-actions are also observed.

Bis(4-methyl-imidazolium) succinate succinic acid solvate.

Project description:In the title compound, 2C(4)H(7)N(2) (+)·C(4)H(4)O(4) (2-)·C(4)H(6)O(4), the asymmetric unit consists of two 4-methyl-imidazolium cations, one succinate dianion and one netrual succinic acid mol-ecule and within the latter components, the C-O, C=O and C O bonds are clearly evidenced from their relative distances. In the crystal structure, the individual components are linked by inter-molecular N-H?O, O-H?O and C-H?O hydrogen bonds into a two-dimensional network parallel to the (101) plane in which R(3) (3)(9), R(3) (3)(12) and R(4) (4)(18) hydrogen-bond motifs are present.

Bis(2-amino-thia-zolium) succinate succinic acid.

Project description:In the title compound, 2C(3)H(5)N(2)S(+)·C(4)H(4)O(4) (2-)·C(4)H(6)O(4), the thia-zolium ring is almost planar, with the maximum deviation from planarity being 0.0056 (8) Å for the C atom carrying the amine substituent. The N atom of the 2-amino-thia-zole mol-ecule is protonated. Both the anion and the acid lie across inversion centres. The crystal packing is consolidated by inter-molecular O-H⋯O, N-H⋯O and C-H⋯O hydrogen bonds. Mol-ecules are stacked down the b axis.

Crystal structure of ethyl 5-acetyl-2-{[(di-methyl-amino)-methyl-idene]amino}-4-methyl-thio-phene-3-carboxyl-ate.

Project description:In the title thio-phene derivative, C13H18N2O3S, the dihedral angles between the thio-phene ring and the [(di-methyl-amino)-methyl-idene]amino side chain (r.m.s. deviation = 0.009 Å) and the -CO2 ester group are 3.01 (16) and 59.9 (3)°, respectively. In the crystal, inversion dimers linked by pairs of C-H⋯O hydrogen bonds generate R 2 (2)(16) loops. The dimers are linked by another weak C-H⋯O inter-action, forming chains along [001]. In addition, weak C-H⋯π inter-actions are observed, which link the chains into (001) layers.

Crystal structure of bis-(N-methyl-N-phenyl-amino)-tris-ulfane.

Project description:The title compound, C14H16N2S3, crystallized with two independent mol-ecules [(1 a ) and (1 b )] in the asymmetric unit. Both mol-ecules display a pseudo-trans conformation. The two consecutive S-S bond lengths of the tris-ulfane unit of mol-ecule (1 a ) are 2.06 (3) and 2.08 (3) Å, and 2.08 (3) and 2.07 (2) Å for mol-ecule (1 b ). Torsion angles about each of the two S-S bonds are 86.6 (2) and 87.0 (2)° for (1 a ), and -84.6 (2) and -85.9 (2)° for (1 b ). The core atoms, viz. the N-S-S-S-N moiety, of the two mol-ecules superimpose well if one is inverted on the other, but the phenyl groups do not. Thus, the two units are essentially conformational enanti-omers. In mol-ecule (1 a ), the two phenyl rings are inclined to one another by 86.7 (3)°, and in mol-ecule (1 b ), by 81.1 (3)°. In the crystal, mol-ecules are linked via C-H⋯π inter-actions, forming sheets lying parallel to (010).

Crystal structure of (2S)-3-methyl-2-[(naphthalen-1-ylsulfon-yl)amino]-butanoic acid.

Project description:The title compound, C15H17NO4S, was synthesized from l-valine and naphthalene-1-sulfonyl chloride. The hydrogen-bonded carb-oxy-lic acid groups form a catemer C(4) motif extending along [100]. The catemer structure is reinforced by a rather long N-H?O hydrogen bond, between the sulfamide N-H group and a carb-oxy-lic acid O atom [H?O = 2.52?(2)?Å], and a C-H?O hydrogen bond.
