Article: (E)-3-(4-Meth-oxy-phen-yl)-3-[3-(4-meth-oxy-phen-yl)-1H-pyrazol-1-yl]prop-2-enal.
[show abstract] [hide abstract]
ABSTRACT: In the title mol-ecule, C20H18N2O3, the pyrazole ring forms a dihedral angle of 2.2 (1)° with its meth-oxy-phenyl substituent and a dihedral angle of 67.2 (1)° with the benzene substituent on the propenal unit. In the crystal, mol-ecules are connected by weak C-H⋯O hydrogen bonds, forming R 2 (2)(26) and R 2 (2)(28) cyclic dimers that lie about crystallographic inversion centres. These dimers are further linked through C-H⋯O and C-H⋯N hydrogen bonds, forming C(8), C(9), C(10) and C(16) chain motifs. These primary motifs are further linked to form secondary C 2 (2)(15) chains and R 2 (2)(18) rings.Acta Crystallographica Section E Structure Reports Online 04/2013; 69(Pt 4):o594-5. · 0.35 Impact Factor -

ABSTRACT: Pyrazoles are classified as both aromatic ring compounds and heterocyclic compounds and are characterized by a 5- membered ring structure composed of three carbon atoms and two nitrogen atoms in adjacent positions in the unsubstituted parent compound. Being so composed and having pharmacological effects on humans, they are classified as alkaloids although they are rare in nature. Pyrazole and its derivatives have been successfully tested for their antifungal (Chen & Li, 1998), antihistaminic (Mishra et al.,1998), anti-inflammatory (Smith et al., 2001), antiarrhythmic and sedative (Bruno et al., 1990), hypoglycemic (Cottineau et al., 2002), antiviral (Baraldi et al., 1998) and pesticidal (Londershausen, 1996) activities. Based on the above specifics and also as part of our continuing work on pyrazole related compounds (Susindran et al., 2010a,b, 2012), we report here the structure of the title pyrazole derivative. The molecular structure of the title compound is shown in Fig. 1. The phenyl rings of the methoxyphenyl groups and the plane of the pyrazole ring form dihedral angles of 2.2 (1)° (with the C31—C36 ring) and 67.2 (1)° (with the C12—C17 ring). The crystal packing is stabilized through weak intermolecular C—H···O and C—H···N interactions (Table 1). Molecules are connected around inversion centres of the unit cell making R2 2 (26) and R2 2 (28) ring motifs (Etter et al., 1990) through C33—H33···O1 and C37—H37B···O2 interactions, respectively. These pairs of dimeric rings are further connected in a head-to-tail fashion by C37—H37B···O2 and C33—H33···O1 contacts, Table 1, to generate sheets of dimers approximately parallel to (112). These contacts also generate C2 2 (15) chains in the ab-plane, Fig 2. Additional chains are generated in the crystal as follows. A C(8) chain forms along the a-axis through a C14—H14···O2 interaction (Fig. 3) while C5—H5···O3 and C18—H18C···N2 contacts generate C(9) and C(10) chains along b. A combination of these contacts also generate an R2 2 (18) ring motif (Fig. 4). Finally a C(16) chain of molecules linked in a head to tail fashion forms along the bc diagonal through a C37—H37C···O1 contact, Fig 5.Acta Crystallographica Section E Structure Reports Online 03/2013; E69:o594–o595. · 0.35 Impact Factor -

ABSTRACT: In the title mol-ecule, C(21)H(14)N(4)O(4)S, the pyrazole ring forms dihedral angles of 45.6 (1), 87.7 (1) and 27.4 (1)° with the phenyl, sulfur-substituted benzene and nitro-substituted benzene rings, respectively. In the crystal, mol-ecules are connected by weak C-H⋯O and C-H⋯N hydrogen bonds into layers parallel to (010).Acta Crystallographica Section E Structure Reports Online 10/2012; 68(Pt 10):o2845. · 0.35 Impact Factor -
