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...

In the title compound, C(9)H(15)N(5)O(3), in which the molecules exhibit orientational disorder, the molecules of the major component are linked by paired N-H...O hydrogen bonds [H...O = 2.37 and 2.39 A, N...O = 2.974 (3) and 3.011 (3) A, and N-H...O = 126 and 128 degrees ] to form a C(8)C(8)[R(2)(2)(6)] chain of rings along [010]. The minor component (6.5% of the molecules) forms a similar cha...

متن کاملChain stopper engineering for hydrogen bonded supramolecular polymers
Supramolecular polymers are linear chains of low molar mass monomers held together by reversible and directional non-covalent interactions, which can form gels or highly viscous solutions if the self-assembled chains are sufficiently long and rigid. The viscosity of these solutions can be controlled by adding monofunctional compounds, which interact with the chain extremities: chain stoppers. W...
متن کامل2-nitrophenoxyacetanilide: a chain of rings generated by C-H...O hydrogen bonds.
In molecules of the title compound, C(14)H(12)N(2)O(4), the conformation is dominated by an intramolecular N-H.O hydrogen bond in which one of the nitro O atoms is the acceptor. The molecules are linked by paired C-H.O hydrogen bonds [H.O = 2.41 A, C.O = 3.2990 (17) A and C-H.O = 156 degrees ] into centrosymmetric R(2)(2)(14) dimers; these dimers are linked weakly into chains of alternating R(2...
