RESUMO
The title compound, C(6)H(4)ClN(3), is essentially planar with the pyrrole and pyrimidine rings inclined to one another by 0.79â (15)°. In the crystal, mol-ecules are connected via pairs of N-Hâ¯N hydrogen bonds, forming inversion dimers. These dimers are linked via C-Hâ¯N inter-actions, forming a two-dimensional network parallel to (10-1).
RESUMO
In the title mol-ecule, C(7)H(7)NO(3), the nitro group is oriented at 14.4â (3)° with respect to the plane of the benzene ring. The crystal structure is stabilized by O-Hâ¯O hydrogen bonds and further consolidated by C-Hâ¯O inter-actions.
RESUMO
In the crystal structure of the title compound, C5H6ClN3, mol-ecules are linked by pairs of N-Hâ¯N hydrogen bonds, forming inversion dimers. These dimers are linked via N-Hâ¯N hydrogen bonds, forming a two-dimensional network lying parallel to (100). Inversion-related mol-ecules are also linked via a slipped π-π inter-action, with a centroid-centroid distance of 3.5259â (11)â Å, a normal separation of 3.4365â (7)â Å and a slippage of 0.789â Å.
RESUMO
In the title compound, C(11)H(9)F(2)N(3)O(2), the triazole ring is planar, with an r.m.s. deviation of 0.0048â Å, and makes a dihedral angle of 77.3â (1)° with the benzene ring. In the crystal, weak inter-molecular C-Hâ¯O and C-Hâ¯N hydrogen bonds link the mol-ecules into chains along the b axis.
RESUMO
The title compound, C(11)H(11)NO(3), was synthesized by the reaction of maleic andydride and phenyl-methanamine. The mol-ecular conformation is stabilized by by an intra-molecular O-Hâ¯O hydrogen bond. In the crystal, mol-ecules are linked by inter-molecular N-Hâ¯O and C-Hâ¯O hydrogen bonds, forming a chain along the b axis.
RESUMO
In the title compound, C(15)H(13)BrN(2), the benzimidazole group is almost planar, as indicated by the dihedral angle of 2.6â (3)° between the best planes through the benzene and imidazole rings. The best plane through the attached benzene makes an angle of 44.5â (2)° with the best plane through the benzimidazole system. C-Hâ¯π inter-actions are observed in the crystal structure.
RESUMO
In the title compound, C(11)H(18)N(4) (2+)·2PF(6) (-), the dihedral angle between the two planar imidozlium rings is 6.1â (2)°. Both [PF(6)](-) anions are disordered [occupancies 0.65â (2):0.35â (2) and 0.59â (5):0.41â (5)]. The crystal packing is stabilized by inter-molecular C-Hâ¯F hydrogen bonds which link two mol-ecules, forming centrosymmetric dimers.
RESUMO
The asymmetric unit of the title compound, C(16)H(20)N(2), contains two independent mol-ecules. The rings in each mol-ecule are oriented at dihedral angles of 78.94â (3) and 77.76â (3)°.
