RESUMEN
In the crystal of the title compound, C11H12O5S2, mol-ecules are linked by O-Hâ¯O hydrogen bonds and C-Hâ¯O inter-actions, forming a three-dimensional network.
RESUMEN
In the title mol-ecule, C20H18N2O3, the pyrazole ring forms a dihedral angle of 2.2â (1)° with its meth-oxy-phenyl substituent and a dihedral angle of 67.2â (1)° with the benzene substituent on the propenal unit. In the crystal, mol-ecules are connected by weak C-Hâ¯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-Hâ¯O and C-Hâ¯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.
RESUMEN
In the title mol-ecule, C(21)H(14)N(4)O(4)S, the pyrazole ring forms dihedral angles of 45.6â (1), 87.7â (1) and 27.4â (1)° with the phenyl, sulfur-substituted benzene and nitro-substituted benzene rings, respectively. In the crystal, mol-ecules are connected by weak C-Hâ¯O and C-Hâ¯N hydrogen bonds into layers parallel to (010).
RESUMEN
In the title compound C(18)H(14)N(2)O, the pendant rings make dihedral angles of 66.1â (1)° and 13.9â (1) with the central ring. In the crystal, two mol-ecules form a cyclic centrosymmetric R(2) (2)(22) dimer through pairs of C-Hâ¯O bonds. These dimers are further connected into zigzag chains extending along the b axis through C-Hâ¯π and C-Hâ¯O inter-actions.
RESUMEN
In the title compound, C(18)H(12)Cl(2)N(2)O, the pyrazole ring is almost planar [r.m.s. deviation = 0.002â Å] while the two chloro-phenyl rings are twisted out from the plane of the pyrazole ring, making dihedral angles of 5.3â (1) and 65.34â (4)°. In the crystal, centrosymmetric R(2) (2)(24) dimers are formed about crystallographic inversion centres through a pair of C-Hâ¯Cl inter-actions. These dimers are further linked through a C-Hâ¯O hydrogen bond, forming a C(8) chain extending along the a axis. C-Hâ¯π inter-actions are also observed.
