Hydrogen-bonded sheets in (E)-2-nitrobenzaldehyde 4-nitrophenylhydrazone and a hydrogen-bonded framework structure in (E)-4-nitrobenzaldehyde 4-nitrophenylhydrazone.
Molecules of (E)-2-nitrobenzaldehyde 4-nitrophenylhydrazone, C13H10N4O4, exhibit a strongly polarized molecular-electronic structure. The molecules are linked into sheets of some complexity, where pairs of hydrogen bonds act co-operatively to generate two independent substructures, each in the form of a chain of rings. In the isomeric compound (E)-4-nitrobenzaldehyde 4-nitrophenylhydrazone, the...
متن کاملDichloridobis(phenyl 2-pyridyl ketone oxime)nickel(II) acetone solvate
The Ni atom in the title compound, [NiCl(2)(C(12)H(10)N(2)O)(2)]·C(3)H(6)O, adopts a distorted octa-hedral geometry, being ligated by four N atoms from two different phenyl 2-pyridyl ketone oxime ligands and two Cl atoms. In the crystal structure, inter-molecular O-H⋯Cl hydrogen bonds link the mol-ecules into a chain structure along [010]. There is a π-π contact between the pyridine rings [cent...
متن کامل2-(Anthracen-9-yl)-10-methoxybenzo[h]quinoline acetone hemisolvate
The asymmetric unit of the title structure, C(28)H(19)NO·0.5C(3)H(6)O, comprises one 2-(anthracen-9-yl)-10-meth-oxy-benzo[h]-quinoline mol-ecule and an acteone mol-ecule with an occupany of 0.5. The solvent mol-ecule is disordered around a centre of symmetry. Its occupancy was determined from NMR data and kept fixed during the refinement. The two conjugated ring systems of the mol-ecule are alm...
متن کامل1-(2-Methyl-5-nitro-1H-imidazol-1-yl)acetone
In the mol-ecule of the title compound, C7H9N3O3, the nitro and carbonyl groups are tilted with respect to the imidazole ring by 9.16 (6) and 65.47 (7)°, respectively. Neighbouring chains are linked via C-H⋯N and C-H⋯O hydrogen bonds forming two-dimensional slab-like networks lying parallel to (01-1).
متن کامل(R)-[1-(2-Chlorophenyl)-2-methoxy-2-oxoethyl][2-(thiophen-2-yl)ethyl]ammonium (+)-camphor-10-sulfonate acetone monosolvate
The title compound, C(15)H(17)ClNO(2)S(+)·C(10)H(15)O(4)S(-)·C(3)H(6)O, was synthesized by N-alkyl-ation of α-amino-(2-chloro-phen-yl)acetate with 2-thienylethyl p-toluene-sulfonate, followed by reaction with (+)-camphor-10-sulfonic acid. In the crystal, the cations and anions are linked through N-H⋯O hydrogen bonds. The thio-phene ring of the cation was found to be disordered over two sites, w...
