title: 1,3,5-Tri-p-tolyl-pentane-1,5-dione.
abstract: In the crystal structure of the title compound, C(26)H(26)O(2), the dihedral angle between the tolyl rings at each end of the 1,5-dione chain is 70.3 (1)°; the tolyl group at the middle of the chain makes dihedral angles of 67.8 (2) and 85.1 (2)° with the terminal rings. One benzene C atom and one methyl-ene C atom inter-act with a carbonyl O atom of an adjacent mol-ecule through C-H⋯O hydrogen bonds, forming chains in the crystal.
