Crystal structure of 3-methyl-1-phenyl-5-(1H-pyrrol-1-yl)-1H-pyrazole-4-carbaldehyde.

ABSTRACT: In the title compound, C15H13N3O, the pyrrolyl and phenyl rings make dihedral angles of 58.99?(5) and 34.95?(5)°, respectively, with the central pyrazole ring. In the crystal, weak, pairwise C-H?O inter-actions across centers of symmetry form dimers, which are further associated into corrugated sheets running approximately parallel to (100) via weak C-H?N inter-actions.

Project description:The title compound, C15H14N4O, crystallizes with two mol-ecules in the asymmetric unit with similar conformations (r.m.s. overlay fit for the 20 non-H atoms = 0.175?Å). In the first mol-ecule, the dihedral angles between the planes of the central pyrazole ring and the pendant phenyl and pyrrole rings are 42.69?(8) and 51.88?(6)°, respectively, with corresponding angles of 54.49?(7) and 49.61?(9)°, respectively, in the second mol-ecule. In the crystal, the two mol-ecules, together with their inversion-symmetry counterparts, are linked into tetra-mers by O-H?N hydrogen bonds. The tetra-mers form layers parallel to (211) through pairwise C-H?? inter-actions.

Crystal structure of 5-[4-(di-methyl-amino)-phen-yl]-3-(4-methyl-phen-yl)-4,5-di-hydro-1H-pyrazole-1-carbaldehyde.

Project description:The title compound, C19H21N3O, comprises a central pyrazole ring which is N-connected to an aldehyde group and C-connected twice to substituted benzene rings. The pyrazole ring is twisted on the C-C single bond, and the least-squares plane through this ring forms dihedral angles of 82.44 (5) and 4.52 (5)° with the (di-methyl-amino)-benzene and p-tolyl rings, respectively. In the crystal, weak C-H⋯O hydrogen bonds link mol-ecules into supra-molecular tubes along the b axis.

Project description:The title compound, C(22)H(24)N(2)OS, has been synthesized as a potent fungicidal agent and its crystal structure determined. In the crystal structure, weak inter-molecular C-H⋯O inter-actions are observed. The dihedral angles between the planes of the pyrazole and phenyl rings, and between the benzene and pyrazole rings are 54.2 (2) and 25.0 (3)°, respectively. The methyl groups of the tert-butyl group are disordered over two positions; the site occupancies are ca 0.65 and 0.35.

1-Phenyl-1H-pyrazole-4-carbaldehyde.

Project description:In the title mol-ecule, C(10)H(8)N(2)O, the five- and six-membered rings form a dihedral angle of 10.14?(9)°. The aldehyde group is almost coplanar with the pyrazole ring to which it is connected [O-C-C-C torsion angle = -179.35?(17)°]. In the crystal, inversion dimers are linked by four C-H?O inter-actions as the carbonyl O atom accepts two such bonds. The dimeric aggregates are linked into supra-molecular layers in the ac plane by C-H?? and ?-? [ring centroid(pyrrole)?ring centroid(phen-yl) = 3.8058?(10)?Å] inter-actions.

3-(4-Meth-oxy-phen-yl)-1-phenyl-1H-pyrazole-4-carbaldehyde.

Project description:Four independent mol-ecules comprise the asymmetric unit of the title compound, C(17)H(14)N(2)O(2). The central pyrazoline ring is flanked by an N-bound benzene ring and a C-bound meth-oxy-substituted benzene ring. The greatest difference between the independent mol-ecules is found in the relative orientations of the benzene rings with the range of dihedral angles being 23.59?(6)-42.55?(6)°. In the crystal, extensive C-H?O inter-actions link mol-ecules into layers parallel to (02[Formula: see text]) and these are linked by C-H?? contacts.
