Crystal structure of (4Z)-4-[(di-methyl-amino)-methyl-idene]-3,5-dioxo-2-phenyl-pyrazolidine-1-carbaldehyde.
In the title compound, C13H13N3O3, the pyrazolidine ring adopts a shallow envelope conformation, with the carbonyl C atom closest to the benzene ring as the flap [deviation of 0.126 (1) Å from the plane through the remaining atoms (r.m.s. deviation = 0.011 Å)]. The dihedral angle between the pyrazolidine ring (all atoms) and the benzene ring is 51.09 (4)°. An extremely short (2.08 Å) intra-molecular C-H⋯O contact is seen. In the crystal, mol-ecules are linked by C-H⋯O bonds, generating [010] chains. Extremely weak C-H⋯π inter-actions are also observed.
