5-[(tert-Butyl-diphenyl-sil-yloxy)meth-yl]pyridazin-3(2H)-one.
In the title compound, C21H24N2O2Si, a new pyridazin-3(2H)-one derivative, the carbonyl group of the heterocyclic ring and the O atom of the silyl ether are located on the same side of the pyridazinone ring and the C-C-O-Si torsion angle is -140.69 (17)°. In the crystal, mol-ecules are linked by pairs of strong N-H⋯O hydrogen bonds into centrosymmetric dimers with graph-set notation R 2 (2)(8). Weak C-H⋯π inter-actions are also observed.
