(E)-2-[(2,4-Dihy-droxy-benzyl-idene)aza-nium-yl]-3-(1H-indol-3-yl)propano-ate monohydrate.

ABSTRACT: In the zwitterionic title compound, C(18)H(16)N(2)O(4)·H(2)O, the dihedral angle between the planes of the benzene and indole rings is 39.20?(8)°. An intra-molecular N-H?O hydrogen bond generates an S(6) ring motif. In the crystal, inter-molecular hy-droxy and water O-H?O(carboxyl-ate) and N(+)-H?O(carboxyl-ate) and indole N-H?O(water) hydrogen bonds give a three-dimensional structure.

2-[(2-Hy-droxy-eth-yl)aza-nium-yl]ethanaminium oxalate monohydrate.

Project description:In the title hydrated mol-ecular salt, C(4)H(14)N(2)O(2+)·C(2)O(4) (2-)·H(2)O, the oxalate dianion is almost planar (r.m.s. deviation = 0.020?Å). In the crystal, the components are linked by N-H?O(water), N-H?O(oxalate) O-H(ammonium)?O(oxalate), O-H(water)?O(oxalate) and O-H(water)?O(ammonium) hydrogen bonds, thereby forming a complex three-dimensional packing motif.

2-Hy-droxy-5-[(E)-(1H-indol-3-yl-methyl-idene)aza-nium-yl]benzoate.

Project description:The zwitterionic title compound, C(16)H(12)N(2)O(3), was obtained as a result of the condensation of 5-amino-salicylic acid and 1H-indole-3-carbaldehyde. The whole mol-ecule is roughly planar: the 4-hy-droxy-anilinic group and the 1H-indole-3-carbaldehyde moieties are only slightly twisted, making a dihedral angle of 7.77?(11)°, whereas, the carboxyl-ate group makes a dihedral angle of 3.34?(45)° with the parent 4-hy-droxy-anilinic group. S(6) ring motifs are formed due to intra-molecular O-H?O hydrogen bonding. In the crystal, inter-molecular N-H?O and C-H?O hydrogen bonds build up pseudo-rings with R(1) (2)(4), R(2) (1)(7) and R(2) (2)(14) ring motifs. These pseudo-dimers are further linked by N-H?O hydrogen bonds into a chain extending along [101]. C-H?? inter-actions also occur, along with offset ?-? inter-actions between the anilinic phenyl and the heterocyclic five-membered rings with a centroid-centroid distance of 3.5716?(19)?Å.

(S)-2-[(2-Hy-droxy-benz-yl)aza-nium-yl]-4-(methyl-sulfan-yl)butano-ate.

Project description:The zwitterionic title compound, C(12)H(17)NO(3)S, is a reduced Schiff base derived from (S)-N-(2-hy-droxy-benzyl-idene)methio-nine. An intra-molecular inter-action between the N-H and carboxyl-ate groups forms a roughly planar (r.m.s. deviation = 0.1405?Å) five-membered ring containing the H(N), N, C?, C(carboxyl-ate) and O atoms in a penta-gonal conformation. In the crystal, a supra-molecular triangle-shaped motif is generated by mol-ecules held together by O-H?O and N-H?O hydrogen bonds.

(2,4-Dihy-droxy-6-meth-oxy-phen-yl)(3,5-dihy-droxy-phen-yl)methanone monohydrate.

Project description:The title benzophenone compound, C(14)H(12)O(6)·H(2)O, was isolated from the bark of Garcinia hombroniana Pierre (Guttiferae). The mol-ecule is twisted, the dihedral angle between the two benzene rings being 59.13?(7)°. The meth-oxy group is approximately coplanar with the attached benzene ring, with a C-O-C-C torsion angle of 1.91?(18)°. The water mol-ecule is disordered over two positions in a 0.555?(19):0.445?(19) ratio. An intra-molecular O-H?O hydrogen bond generates an S(6) ring motif. The crystal structure is stabilized by inter-molecular O-H?O hydrogen bonds. These inter-actions link the mol-ecules into sheets parallel to the ac plane. The sheets are stacked along the b axis by ?-? inter-actions, with centroid-centroid distances of 3.6219?(7)?Å. A weak O-H?? inter-action was also noted.

(E)-1-(2,4-Dihy-droxy-phen-yl)-3-(4-hydroxy-phen-yl)prop-2-en-1-one monohydrate.

Project description:In the title compound, C(15)H(12)O(4)·H(2)O, the two benzene rings are not coplanar, making a dihedral angle of 7.24 (16)°. An intra-molecular hy-droxy-carbonyl O-H⋯O hydrogen bond occurs. In the crystal, four inter-molecular O-H⋯O hydrogen bonds involving the hy-droxy residues, the carbonyl group and the water mol-ecule lead to the formation of a three-dimensional network. The supra-molecular structure is further stabilized by weak C-H⋯O inter-actions.

Crystal structures of the 1:1 salts of 2-amino-4-nitro-benzoate with each of (2-hy-droxy-eth-yl)di-methyl-aza-nium, tert-but-yl(2-hy-droxy-eth-yl)aza-nium and 1,3-dihy-droxy-2-(hy-droxy-meth-yl)propan-2-aminium.

Project description:The crystal and mol-ecular structures of the title mol-ecular salts, C4H12NO+·C7H5N2O4 -, (I), C6H16NO+·C7H5N2O4 -, (II), and C4H12NO3 +·C7H5N2O4 -, (III), are described. The common feature of these salts is the presence of the 2-amino-4-nitro-benzoate anion, which exhibit non-chemically significant variations in the conformational relationships between the carboxyl-ate and nitro groups, and between these and the benzene rings they are connected to. The number of ammonium-N-H H atoms in the cations increases from one to three in (I) to (III), respectively, and this variation significantly influences the supra-molecular aggregation patterns in the respective crystals. Thus, a linear supra-molecular chain along [100] sustained by charge-assisted tertiary-ammonium-N-H?O(carboxyl-ate), hy-droxy-O-H?O(carboxyl-ate) and amino-N-H?O(carboxyl-ate) hydrogen-bonds is apparent in the crystal of (I). Chains are connected into a three-dimensional architecture by methyl-C-H?O(hy-droxy) and ?-? inter-actions, the latter between benzene rings [inter-centroid separation = 3.5796?(10)?Å]. In the crystal of (II), a supra-molecular tube propagating along [901] arises as a result of charge-assisted secondary-ammonium-N-H?O(carboxyl-ate) and hy-droxy-O-H?O(carboxyl-ate) hydrogen-bonding. These are connected by methyl-ene- and methyl-C-H?O(nitro) and ?-? stacking between benzene rings [inter-centroid separation = 3.5226?(10)?Å]. Finally, double-layers parallel to (100) sustained by charge-assisted ammonium-N-H?O(carboxyl-ate), ammonium-N-H?O(hy-droxy) and hy-droxy-O-H?O(carboxyl-ate) hydrogen-bonds are apparent in the crystal of (III). These are connected in a three-dimensional architecture by amine-N-H?O(nitro) hydrogen-bonds.
