N-[(E)-Quinoxalin-2-ylmethyl-idene]-1H-indazol-5-amine.

ABSTRACT: In the title mol-ecule, C(16)H(11)N(5), the mean planes of the quinoxaline and indazole fragments form a dihedral angle of 10.62?(5)°. In the crystal, weak inter-molecular N-H?N hydrogen bonds link the mol-ecules into zigzag chains extending in the [001] direction. The crystal packing also exhibits ?-? inter-actions [centroid-centroid distances of 3.7080?(2) and 3.8220?(5)?Å], which form stacks of the mol-ecules parallel to the a axis.

In the title mol-ecule, C(16)H(11)N(5), the mean planes of the quinoxaline and indazole fragments form a dihedral angle of 10.62 (5)°. In the crystal, weak inter-molecular N-H⋯N hydrogen bonds link the mol-ecules into zigzag chains extending in the [001] direction. The crystal packing also exhibits π-π inter-actions [centroid-centroid distances of 3.7080 (2) and 3.8220 (5) Å], which form stacks of the mol-ecules parallel to the a axis. ...[more]

N,N'-Bis[(E)-quinoxalin-2-ylmethyl-idene]-ethane-1,2-diamine.

Project description:In the mol-ecule of the title compound, C(20)H(16)N(6), the central C-C bond lies on a crystallographic inversion centre. The quinoxalidine ring is nearly planar, with a maximum deviation of 0.021?(2)?Å from the mean plane. The crystal structure is stabilized by inter-molecular C-H?N inter-actions, leading to the formation of a layer-like structure, which extends along the a axis.

N'-(5-Bromo-1H-indol-3-ylmethyl-idene)-3,4,5-trihydroxy-benzohydrazide.

Project description:The two aromatic parts of the title mol-ecule, C(16)H(12)BrN(3)O(4), are connected through a conjugated -CH=N-NH-C(O)- fragment to furnish an almost planar mol-ecule. Adjacent mol-ecules are linked by N-H⋯O and O-H⋯O hydrogen bonds into a three-dimensional network. An intramolecular O-H⋯O link also occurs.

2-Hydr-oxy-(2-methyl-1H-indol-3-ylmethyl-idene)benzohydrazide ethanol solvate.

Project description:In the title compound, C(17)H(15)N(3)O(2)·C(2)H(6)O, Schiff base molecules are linked by a hydr-oxy-amido hydrogen bond into a helical chain running along the b axis. This chain is consolidated by two other hydrogen bonds; the ethanol solvent mol-ecule is a hydrogen-bond donor to the amide group and a hydrogen-bond acceptor for the indolyl NH group of an adjacent Schiff base mol-ecule.

2-[(E)-(1H-Pyrrol-2-ylmethyl-idene)hydrazinyl]pyridine monohydrate.

Project description:The title hydrate, C(10)H(10)N(4)·H(2)O, shows a small twist in the hydro-zone derivative, the dihedral angle between the pyridine and pyrrole rings being 11.08?(12)°. The pyridine and pyrrole N atoms lie to the same side of the mol-ecule being sustained in place by hydrogen-bonding inter-actions with the water mol-ecule. Further inter-molecular O-H?N and N-H?O hydrogen bonding leads to the formation of supra-molecular arrays in the ab plane.

3,4,5-Trihydr-oxy-N'-(1H-indol-2-ylmethyl-idene)benzohydrazide-1H-indole-2-carbaldehyde azine-methanol (2/1/2).

Project description:The title compound, 2C(16)H(13)N(3)O(4)·C(18)H(14)N(4)·2CH(4)O, was crystallized from the reaction between 3,4,5-trihydroxy-benzoyl-hydrazine and indole-2-carbaldehyde in a mixture of ethanol and methanol. The compound is a stoichiometric 2:1 cocrystal of the methanol-solvated reaction product, 3,4,5-trihydr-oxy-N'-(1H-indol-2-ylmethyl-idene)benzohydrazide and 1H-indole-2-carbaldehyde azine that arose unexpectedly during the synthesis. The former mol-ecules are linked by O-H?O hydrogen bonds and also by ?-? stacking inter-actions between benzoyl-hydrazide rings into a two-dimensional network. The methanol solvent mol-ecules are hydrogen bonded to this network. The centrosymmetric azine mol-ecules are not engaged in hydrogen bonding.

3-Methyl-4-[(E)-3-thien-ylmethyl-idene-amino]-1H-1,2,4-triazole-5(4H)-thione.

Project description:The asymmetric unit of the title compound, C(8)H(8)N(4)S(2), contains two crystallographically independent mol-ecules. The thio-phene ring of one mol-ecule is disordered over two positions with refined site occupancies of 0.6375?(19) and 0.3625?(19). One mol-ecule is almost planar and the other one is twisted, the dihedral angles between the thio-phene and triazole rings being 7.28?(7) and 48.9?(2)° [48.5?(4)° for the minor component], respectively. An intra-molecular C-H?S hydrogen bond stabilizes the mol-ecular conformation of the planar molecule. In the crystal, the two mol-ecules are inter-connected by N-H?S hydrogen bonds into dimers, which are further consolidated into chains along the b axis by C-H?N hydrogen bonds. Weak C-H?? and ?-? inter-actions [centroid-centroid distance = 3.5149?(7)?Å] are also observed.

Bis[N,N-bis-(1-allyl-1H-benzimidazol-2-ylmethyl-?N)benzyl-amine-?N]cadmium dipicrate.

Project description:The crystal structure of the title compound, [Cd(C(29)H(29)N(5))(2)](C(6)H(2)N(3)O(7))(2), consists of Cd(II) complex cations and picrate anions. In the complex cation, the Cd(II) ion is chelated by two bis-(1-allyl-benzimidazol-2-ylmeth-yl)benzyl-amine (babb) ligands in a distorted octa-hedral geometry. Extensive C-H?O hydrogen bonding occurs between cations and anions in the crystal structure.
