2,4-Dimethylbenzaldehyde isonicotinoylhydrazone trihydrate: a three-dimensional hydrogen-bonded framework structure.
In the title compound, C(15)H(15)N(3)Ox3H(2)O, two of the three water molecules exhibit disorder. The molecular components are linked into a three-dimensional framework by a combination of N-H...O, O-H...N and O-H...O hydrogen bonds.
متن کامل2-(4-Nitrophenoxy)benzoic acid: a three-dimensional hydrogen-bonded framework in a triclinic structure having Z' = 3.
The title compound, C(13)H(9)NO(5), crystallizes in space group P-1, with Z' = 3. The molecules are linked by O-H...O hydrogen bonds [H...O = 1.79-1.81 A, O...O = 2.625 (3)-2.648 (3) A and O-H...O = 172-176 degrees ] into two types of R(2)(2)(8) dimer, only one of which is centrosymmetric. An extensive series of soft hydrogen bonds, of C-H...O and C-H...pi(arene) types, links the dimers into a ...
متن کاملThree-dimensional hydrogen-bonded framework structures in flunarizinium nicotinate and flunarizinediium bis(4-toluenesulfonate) dihydrate.
The structures of two salts of flunarizine, namely 1-bis[(4-fluorophenyl)methyl]-4-[(2E)-3-phenylprop-2-en-1-yl]piperazine, C26H26F2N2, are reported. In flunarizinium nicotinate {systematic name: 4-bis[(4-fluorophenyl)methyl]-1-[(2E)-3-phenylprop-2-en-1-yl]piperazin-1-ium pyridine-3-carboxylate}, C26H27F2N2(+)·C6H4NO2(-), (I), the two ionic components are linked by a short charge-assisted N-H.....
متن کاملHydrogen-bonded dimers in 2-nitrobenzaldehyde hydrazone and a three-dimensional hydrogen-bonded framework in 3-nitrobenzaldehyde hydrazone.
Molecules of 2-nitrobenzaldehyde hydrazone, C7H7N3O2, where Z' = 2, are linked by two N-H...N hydrogen bonds into isolated dimers, whereas in the isomeric 3-nitrobenzaldehyde hydrazone, where Z' = 1, the molecules are linked by one N-H...O hydrogen bond and one N-H...N hydrogen bond into a three-dimensional framework structure.
متن کاملA two-dimensional hydrogen bonded organic framework self-assembled from a three-fold symmetric carbamate.
A flexible organic sheet spontaneously assembled under mild conditions from a tri-carbamate. By introducing cyclohexyl side chains as 'pillars' between the sheets, a hydrogen bonded organic framework was formed which displayed a capacity for accommodating and releasing guest molecules. The guest size/shape selectivity of the lamellar framework was demonstrated by testing with various guests.
