(3-Hydroxy-2-methyl-1-(p-tolyl)-4-pyridinonato)diphenylboron has been prepared in high yield by the reaction of 3-hydroxy-2-methyl-1-(p-tolyl)-4-pyridinone with diphenylborinic acid.Crystals of the hemi-acetone solvate are triclinic, a = 15.119(2), b = 16.528(1), c = 9.5802(9) Angstroem, α = 98.721(6), β = 93.344(8), γ = 102.443(6) deg, Z = 4, space group P1-.The structure was solved by direct methods and was refined by full-matrix least-squares procedures to R = 0.050 and Rw = 0.065 for 4330 reflections with I >/= 3?(I).The five-membered chelate rings in both of the two crystallographically independent molecules have flattened B-envelope conformations (maximum deviations from the mean planes = 0.114(4) and 0.065(5) Angstroem).Mean bond lengths O-B = 1.553 and C-B = 1.599 Angstroem are consistent with intermediate strength binding of the diphenylboron moiety by the O,O-chelating ligand.
