A second monoclinic polymorph of methyl 4-hydroxy-benzoate.

ABSTRACT: A second monoclinic polymorph of methyl 4-hydroxy-benzoate, C(8)H(8)O(3), 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 mol-ecules, as observed in the previous form. The crystal structure is stabilized by inter-molecular O-H?O and C-H?O hydrogen bonds and C-H?? inter-actions, which link the mol-ecules into a three-dimensional network.
