The reaction of zinc acetate and 2-methyl-8-hydroxyquinoline in methanol yielded the centrosymmetric dinuclear title compound, [Zn2(C10H8NO)2(CH3CO2)2(CH3OH)2], which has the Zn atom within a distorted NO4 trigonal–bipyramidal coordination geometry. Methanol–acetate O—H⋯O hydrogen bonds link the dinculear units into a linear supramolecular chain extending parallel to .
Unlike 8-hydroxyquinoline, which yields a large number of metal derivatives, 2-methyl-8-hydroxyquinoline forms only a small number of metal chelates. Besides a related chloride salt (Sattarzadeh et al., 2009 ▶), there is only one crystal structure report of another zinc derivative; for aquabis(2-methylquinolin-8-ato)zinc, see: da Silva et al. (2007 ▶).
