4-(4-Meth-oxy-phen-yl)-2-methyl-but-3-yn-2-ol

Abstract

The mol-ecular structure of the title compound, C(12)H(14)O(2), features a nearly coplanar arrangement including the aromatic ring, the C C-C group and the ether O atom. The maximum deviation from the least-squares plane of these ten atoms is 0.0787 (8) Å for the ether O atom. In the crystal, mol-ecules are connected via O-H⋯O hydrogen bonds (involving the hy-droxy O atom both as hydrogen-bond donor and acceptor) and weaker (ar-yl)C-H⋯π(ar-yl) contacts, leading to the formation of strands running parallel to the b axis. Further stabilization results from weaker (meth-yl)C-H⋯π(acetyl-ene) inter-actions between different strands.
