Synthesis and crystal structure of 1,3,5-tris-[(1 H-benzotriazol-1-yl)meth-yl]-2,4,6-tri-ethyl-benzene

In the crystal structure of the title compound, C₃₃H₃₃N₉, the tripodal mol-ecule exists in a conformation in which the substituents attached to the central arene ring are arranged in an alternating order above and below the ring plane. The three benzotriazolyl moieties are inclined at angles of 88.3 (1), 85.7 (1) and 82.1 (1)° with respect to the mean plane of the benzene ring. In the crystal, only weak mol-ecular cross-linking involving C-H⋯N hydrogen bonds is observed.
