title: 1,3,5-Tris{[3-(1H-benzotriazol-1-ylmeth-yl)phen-oxy]meth-yl}-2,4,6-trimethyl-benzene.
abstract: In the title compound, C(51)H(45)N(9)O(3), three 1-(1H-benzotriazol-1-ylmeth-yl)-3-phen-yloxy (bmph) ligands are bonded to the central benzene ring in an asymmetric arrangement, two bmph located on one side of the central benzene ring and the other bmph located on the opposite side of the central benzene ring. The dihedral angles between the central benzene ring and the three pendant phenoxy rings are 76.71 (14), 67.81 (13) and 70.67 (16)°. In the crystal structure, one bmph is disordered over two sites in a 0.611 (5):0.389 (5) ratio. Some of the methyl H atoms are equally disordered over two sets of sites. Inter-molecular C-H⋯N hydrogen bonding is present in the crystal structure.
