2-(4-Chloro-phen-yl)-5-(3,4-dimethoxy-pheneth-yl)-6,7-dihydro-pyrazolo[1,5-a]pyrazin-4(5H)-one.

ABSTRACT: In the title compound, C(22)H(22)ClN(3)O(3), the dihedral angles between the planes of the benzene rings and the pyrazole ring are 16.05?(10) and 84.84?(10)°. The conformation of the six-membered heterocyclic ring is close to a screw-boat. The crystal packing is stabilized by weak inter-molecular C-H?O inter-actions and is also consolidated by C-H?? inter-actions.

In the title compound, C(22)H(22)ClN(3)O(3), the dihedral angles between the planes of the benzene rings and the pyrazole ring are 16.05 (10) and 84.84 (10)°. The conformation of the six-membered heterocyclic ring is close to a screw-boat. The crystal packing is stabilized by weak inter-molecular C-H⋯O inter-actions and is also consolidated by C-H⋯π inter-actions. ...[more]
