(E)-3-Phenyl-3-(3-phenyl-1H-1-pyrazolyl)-2-propenal
In the title compound C(18)H(14)N(2)O, the pendant rings make dihedral angles of 66.1 (1)° and 13.9 (1) with the central ring. In the crystal, two mol-ecules form a cyclic centrosymmetric R(2) (2)(22) dimer through pairs of C-H⋯O bonds. These dimers are further connected into zigzag chains extending along the b axis through C-H⋯π and C-H⋯O inter-actions.

In the title compound, C(8)H(8)N(4)·C(8)H(8)N(4), two tautomers, viz. 3-phenyl-1,2,4-triazol-5-amine and 5-phenyl-1,2,4-triazol-3-amine, are crystallized together in equal amounts. The 3-phenyl-1,2,4-triazol-5-amine mol-ecule is essentially planar; the phenyl ring makes a dihedral angle of 2.3 (2)° with the mean plane of the 1,2,4-triazole ring. In the 5-phenyl-1,2,4-triazol-3-amine tautomer, t...

In the title compound, C(20)H(18)N(2)O, the pyrazole ring adopts a planar conformation. The C-N bond lengths in the pyrazole ring are shorter than a standard C-N single bond (1.443 Å), but longer than a standard double bond (1.269 Å), indicating electron delocalization. The propenal group assumes an extended conformation. Inter-molecular C-H⋯O hydrogen bonds connect mol-ecules into cyclic centr...

In the title compound, C(25)H(18)N(2)O(3)S, the indole moiety is planar and makes a dihedral angle of 89.95 (09)° with the phenyl ring of the sulfonyl substituent. The mol-ecular conformation features a weak C-H⋯N short contact and the crystal packing reveals a weak C-H⋯O hydrogen bond.

In the title compound, C(28)H(21)N, the planar pyrrole ring makes dihedral angles of 1.5 (2), 42.4 (2), 65.4 (2) and 79.7 (1)°, with the least squares planes of the four phenyl rings. The mol-ecular structure and crystal packing are stabilized by weak inter- and intra-molecular C-H⋯π inter-actions.
