(1H-Pyrrol-2-ylmethylidene)(3-{[(1H-pyrrol-2-ylmethylidene)amino]methyl}benzyl)amine
In the title compound, C(18)H(18)N(4), the dihedral angles between the pyrrole rings and the phenyl ring are 85.07 (8)° and 77.13 (9)°. Inter-molecular N-H⋯N hydrogen bonds contribute to the stabilization of the crystal packing.
متن کامل(E)-Ethyl 2-cyano-3-(1H-pyrrol-2-yl)acrylate
All the non-H atoms of the title compound, C(10)H(10)N(2)O(2), are nearly in the same plane with a maximum deviation of 0.093 (1) Å. In the crystal, adjacent mol-ecules are linked by pairs of inter-molecular N-H⋯O hydrogen bonds, generating inversion dimers with R(2) (2)(14) ring motifs.
متن کامل4-[2-(4-Fluorophenyl)-1H-pyrrol-3-yl]pyridine
In the crystal structure of the title compound, C(15)H(11)FN(2), the pyrrole ring makes dihedral angles of 33.19 (9) and 36.33 (10)° with the pyridine and 4-fluoro-phenyl rings, respectively. The pyridine ring makes a dihedral angle of 46.59 (9)° with the 4-fluoro-phenyl ring. In the crystal structure, an N-H⋯N hydrogen bond joins the mol-ecules into chains.
متن کامل3-Benzamido-1-benzoyl-1H-pyrrol-2(5H)-one
In the title compound, C(18)H(14)N(2)O(3), one of the phenyl rings is almost coplanar with the pyrrole ring [dihedral angle = 2.56 (14)°], whereas the other one is tilted by 63.01 (6)° with respect to the pyrrole ring. Since the NH group is shielded from possible acceptors, this group is not involved in hydrogen bonding.
