Single crystals of a mixed-ligand cadmium complex of the composition Cd(PHBA)2(MEA) 2 are grown from the solution of Cd(CH3OO)2, p-hydroxybenzoic acid (PHBA) and monoethanolamine (MEA) in aqueous ethanol. The crystallographic data are as follows: a = 11.6400(2) Å, b = 10.1363(1) Å, c = 16.6296(2) Å, β = 93.937(1)°, space group I2/a, V = 1957.44(5) Å3, Z = 4. In the complex molecule located on the twofold axis, ligands of both types are bidentately bound to the cadmium ion having the coordination number 8. In the crystal structure, two H bonds of the O–H•••O type combine complex molecules into layers parallel to the ab plane.
