In the title tetra­nuclear compound, [Cu4(C7H14NO)4Cl4], each CuII cation is N,O-chelated by a piperidineethanolate anion and coordinated by a Cl- anion and two O atoms from neighboring piperidine­ethano­late anions in a distorted NO3Cl square-pyramidal geometry. The deprotonated hydroxyl groups of the piperidineethanolate anions bridge CuII cations, forming the tetra­nuclear complex. All piperidine rings display a chair conformation. In the crystal, there are no significant inter­molecular inter­actions present. The crystal studied was an inversion twin refined with a minor component of 0.18 (5).
