title: The cocrystal 2-hydr-oxy-4-methyl-N-propanoylbenzohydrazide-2-hydr-oxy-N-(2-hydr-oxy-4-methyl-benzo-yl)-6-methyl-benzohydrazide (2/1).
abstract: The asymmetric unit of the title compound, 2C(11)H(14)N(2)O(3)·C(16)H(16)N(2)O(4), contains one mol-ecule of 2-hydr-oxy-4-methyl-N-propanoylbenzohydrazide and one-half of a mol-ecule of 2-hydr-oxy-N-(2-hydr-oxy-4-methyl-benzo-yl)-6-methyl-benzohydrazide. The latter is located on a centre of inversion. Intra-molecular N-H⋯O inter-actions stabilize the conformations of both mol-ecules. The crystal structure is stabilized by inter-molecular N-H⋯O and O-H⋯O hydrogen bonds.
