6-tert-Butyl-4-[(4-hy-dr-oxy-methyl-2H-1,2,3-triazol-2-yl)meth-yl]-2H-chromen-2-one

摘要

In the title compound, C17H19N3O3, the triazole ring and the chromene ring system [maximum deviation = 0.018?(2)?? for the O atom] bridged?via?a methyl-ene C atom, are inclined to one another by 73.2?(1)°. In the crystal, mol-ecules are linked by O—H?N hydrogen bonds, forming zigzag chains along [001]. The chains are linked by C—H?O hydrogen bonds, forming layers parallel to (010), and these layers are linked by C—H?π?and?π–π?inter-actions [intercentroid distance = 3.557?(1)??], forming a three-dimensional newwork. The hy-droxy-methyl group at the 4-position of the triazole ring is disordered over two sets of sites, with a refined occupancy ratio of 0.418?(11):0.584?(11).
