The pigment (Y83) crystallises in the monoclinic system, space group P21/c, with two molecules in the unit cell. The molecules exist in the bisketohydrazone tautomeric form and have crystallographic Ci symmetry. The intramolecular hydrogen bonding normally associated with this structural arrangement is observed, but there is no intermolecular hydrogen bonding. The crystal structure differs from those of previously reported Diarylide Yellow pigments (Y12, Y13, Y14 and Y63) in that the molecules are more nearly planar and the packing arrangement involves simple inclined stacks. The difference in crystal packing for Y83 is consistent with its inability to form solid solutions with the other pigments. The colour properties and technical performance of the pigment are discussed in relation to its crystal structure.

The molecular structure of silyl acetate has been determined in the gas phase by electron diffraction and in the crystalline state by X-ray diffraction. The Si–O bond length is 1.685(3)Å in the gas and 1.696(4)Å in the solid. In both phases the heavy-atom skeleton is almost planar with the Si–O and CO bonds arranged cis to one another giving intramolecular Si ⋯ O (carbonyl) distances of 2.795(14)Å(gas) and 2.832(4)Å(solid). The crystal structure is distinguished by having unusually short Si ⋯ O (carbonyl) intermolecular contacts of length 2.721 (4)Å; these interactions exhibit the stereospecificity associated with secondary bonds. Solid methyl acetate, studied to provide a reference structure, has no short intermolecular contacts.
