RESUMO
In the title compound, C25H14F3N3O3, the dihedral angle between the planes of the benz[4,5]imidazo[1,2-a]pyrimidine unit (r.m.s. deviation = 0.035â Å) and the benzochromene ring system (r.m.s. deviation = 0.106â Å) is 72.82â (5)°. In the crystal, mol-ecules are linked by C-Hâ¯O inter-actions, generating [010] C(9) chains. A weak aromatic π-π stacking inter-action [centroid-centroid separation = 3.5376â (15)â Å] is also observed.
RESUMO
In the title compound, C17H14ClNOS, the aromatic rings are inclined to one another by 64.22â (9)°. The acrylo-nitrile group (C=C-C N) is planar to within 0.003â (2)â Å, with the S atom and the methyl C atom displaced from this plane by 0.2317â (6) and -0.637â (2)â Å, respectively. In the crystal, mol-ecules are linked via pairs of C-Hâ¯π inter-actions, forming inversion dimers. There are no other significant inter-molecular inter-actions present.
RESUMO
In the title compound, C24H20N4O2, the pyrazole ring makes dihedral angles of 47.57â (10)° and 30.56â (11)° with its N-bound and C-bound phenyl groups, respectively. The C-N-N-C group that links the two carbonyls has a torsion angle of 81.5â (2)°. The torsion angles between the carbonyl groups and their adjacent pyrazole and phenyl rings are 125.89â (19) and 164.22â (17)°, respectively. In the crystal, pairs of mol-ecules are linked by N-Hâ¯O hydrogen bonds into R 2 (2)(10) ring motifs, which in turn link to form chains that propagate parallel to the c-axis direction.
