Description:
In the title compound, C21H24N2O2Si, the carbonyl group of the heterocyclic ring and the O atom of the silyl ether group are placed toward opposite sides and thetert-butyl and pyridazinone moieties areanti-oriented across the Si—O bond [torsion angle = −168.44 (19)°]. In the crystal, molecules are assembled into inversion dimers through co-operative N—H...O hydrogen bonds between the NH groups and O atoms of the pyridazinone rings of neighbouring molecules. The dimers are linked by π–π interactions involving adjacent pyridazinone rings [centroid–centroid distance = 3.8095 (19) Å], generating ladder-like chains along theb-axis direction. The chains are further linked into a two-dimensional network parallel to theabplane through weak C—H...π interactions.
