The title compound, a bis-5,5'-triazole, C(38)H(28)N(6)O(4), was observed as a side-product from the Sharpless-Meldal click reaction of the corresponding coumarin alkyne and benzyl-azide. Although the compound was present as a minor component, it crystallized in preference to the major product. The two triazole rings are almost orthogonal to each other [dihedral angle = 83.8 (1)°]. However the 4 and 4' coumarin systems are close to coplanar with their respective triazole rings [23.6 (1) and 15.1 ...[more]
