(E)-3-(4-Meth-oxy-phen-yl)-3-[3-(4-meth-oxy-phen-yl)-1H-pyrazol-1-yl]prop-2-enal.

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.

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 mot ...[more]

(E)-3-(4-Bromo-phen-yl)-3-[3-(4-bromo-phen-yl)-1H-pyrazol-1-yl]prop-2-enal.

Project description:There are two crystallographically independent mol-ecules in the asymmetric unit of the title compound, C(18)H(12)Br(2)N(2)O.
