In the title compound, [Cu(C7H5O3)2(C5H5N)2], the Cu atom is located on an inversion center and is coordinated by the N atoms of the two pyridine ligands, trans to each other, and to the carboxylate O atoms of two bidentate 4-hydroxybenzoate ligands [Cu—O = 1.9706 (10) and 2.5204 (11) Å]. Hydrogen bonding between hydroxy H and carboxylate O atoms results in a layer structure parallel to the ab plane.
