In the title compound, [Cd(C14H10NO3)2(H2O)2], which crystallizes with Z = 4 in the space group C2c, the Cd atom is located on a twofold rotation axis and coordinated by six O atoms from two water molecules and two carboxylate groups of two planar 4-(2-hydroxybenzylideneamino)benzoate ligands, with a dihedral angle of 85.6 (1) degrees between them. Strong O-H...O hydrogen bonding in the coordination sphere, together with pi-pi stacking interactions, assemble the molecules into two-dimensional layers.
