%X As a contribution towards a study of the relative disposition of adjacent carbonyl groups in polycarbonyl compounds, the crystal structures of 1,3-diphenylpropane-1,2,3-trione (1), 1,4-diphenyl- butane-1,2,3,4-tetraone (3), 2,4-dihydroxy-2,5-diphenylfuran-3(2H)-one (benzoylformoin) (7) and 3,3-dihydroxy-1,4-diphenylbutane-1,2,4-trio (8) have been determined by X-ray diffraction from diffractometer data at 295 K and refined by least-squares techniques to residuals of 0.036 (942 'observed' reflections), 0.029 (979), 0.067 (941) and 0.045 (1661), respectively. Crystals of 1,3-diphenylpropane-1,2,3-trione are triclinic, P1, a 9.756(4), b 8.813(3), c 8.303(3) Å,&#945; 68.56(2), &#946; 67.53(3), &#947; 89.11(3)º, Z 2. Crystals of 1,4-diphenylbutane-1,2,3,4-tetraone are monoclinic P21/c, a 10.641(2), b 8.381(2), c 14.710(4) Å, &#946; 91.70(2)º, Z 4. 2,4-Dihydroxy-2,5- diphenylfuran-3(2H)-one also forms monoclinic crystals, P21/c, a 5.741(4), b 9.276(7), c 24.31(2) Å, &#946; 106.26(5)º, Z 4. Crystals of 3,3-dihydroxy-1,4-diphenylbutane-1,2,4-trine are triclinic, P1, a 13.08(1), b 12.43(1), c 8.895(8) Å, &#945; 82.54(8), &#946; 81.87(7), &#947; 78.61(7)º, Z 4.
