Abstract

Crystal and molecular structure of 2-(o-hydroxyphenyl)-4,6-diphenylpyridine C23H17NO (I) has been studied by single crystal XRD. The structure (monoclinic, space group P21/c, a = 8.757(2) Å, b = 20.682(4) Å, c = 9.743(2) Å, β = 108.14(2)°, Z = 4) was solved by the direct method and refined anisotropically in the full-matrix approximation to R = 0.076 using all 2660 measured independent reflections (automated diffractometer CAD-4, CuKα). OH group of the molecule of I is disordered in the crystal over three positions with occupation factors 70%, 15% and 15%. The structure contains a very strong intramolecular hydrogen bond O-H⋯N disordered over three directions.
