3-Nitro-5-(4-pyridinio)benzoate
The title compound, C(12)H(8)N(2)O(4), crystallizes as a zwitterion in which the pyridyl N atom is protonated. The dihedral angle between the benzene and pyridinium rings is 27.9 (2)°. In the crystal, N-H⋯O hydrogen bonds link adjacent zwitterions into a three-dimensional structure.

In the title compound, C(10)H(11)N(3)O(2), the nitro group is essentially coplanar with the aromatic ring [dihedral angle = 1.3 (3)°] and forms an intra-molecular amine-nitro N-H⋯O hydrogen bond. In the crystal, weak inter-molecular aromatic C-H⋯O(nitro) hydrogen bonds link the mol-ecules. Weak aromatic ring π-π inter-actions [minimum ring centroid separation = 3.7744 (13) Å] are also present.

In the title pyrazole compound, C(22)H(17)N(3)O(4), an intra-molecular C-H⋯O contact generates a seven-membered ring, producing an S(7) ring motif. The furan and pyrazole rings are essentially planar [maximum deviations = 0.004 (1) and 0.004 (2) Å, respectively] and are almost coplanar, making a dihedral angle of 3.75 (10)°. One of the methyl-phenyl groups is inclined to the pyrazole ring, as i...

In the title compound, C(21)H(14)ClN(3)O(5), an intra-molecular C-H⋯O hydrogen bond generates an S(7) ring motif and the furan and pyrazole rings are almost coplanar, making a dihedral angle of 1.98 (5)°. The pyrazole ring is inclined at dihedral angles of 47.59 (4) and 7.27 (4)° to the chloro-phenyl and methoxy-phenyl groups, respectively. The nitro group is almost coplanar to its attached fur...
متن کاملMethyl 2-benzyl-5-[1-(4-methoxyphenyl)-4-oxo-3-phenylazetidin-2-yl]-4-nitro-3-phenylpyrrolidine-2-carboxylate
In the title mol-ecule, C(35)H(33)N(3)O(6), the pyrrolidine ring adopts a twist conformation. The mol-ecules are paired into centrosymmetric dimers by weak inter-molecular C-H⋯O hydrogen bonds. The dimers inter-act further again via C-H⋯O hydrogen bonds and N-H⋯O intramolecular interaction also stabilize the crystal packing.
