Abstract
A second monoclinic polymorph of methyl 4-hydroxybenzoate, C8H8O3, is reported. The unit-cell dimensions are different from those of the previously reported monoclinic form [Vujovic & Nassimbeni (2006 ▶). Cryst. Growth Des. 6, 1595–1597]. The asymmetric unit contains three crystallographically independent molecules, as observed in the previous form. The crystal structure is stabilized by intermolecular O—H⋯O and C—H⋯O hydrogen bonds and C—H⋯π interactions, which link the molecules into a three-dimensional network.
