摘要

In the title compounds, C10H8O2, (I), and C13H14O3, (II), the 2-acetyl-4-ethynylphenol unit displays a planar geometry, which is stabilized by an intra-molecular O—H?O hydrogen bond. The crystal structure of (I) is constructed of infinite strands, along [101], of C—H?O=C hydrogen-bonded mol-ecules, which in turn are linked by C—H?π inter-actions. In the crystal of (II), which crystallized with three independent mol-ecules per asymmetric unit, the non-polar parts of the mol-ecules form hydro-phobic layered domains, parallel to (10-1), which are separated by the polar groups. While the 2-acetyl-phenol part of the mol-ecules are involved in O—H?O=C hydrogen bonding, the ternary OH groups creates a cyclic pattern of O—H?O hydrogen bonds.
