Abstract: In the trinuclear title compound, [Cu₃Cl₄(C₁₇H₃₈N₃O₂)₂]·2H₂O or [Cu(AcC₁₁tacn)Cl·H₂O]₂·CuCl₂ [tacn is 1,4,7-triazacyclononone], two Cu atoms are coordinated by a bifunctionalized 1-acetato-4-undecyl-1,4,7-triazacyclononone (AcC₁₁tacn) macrocycle and are five-coordinate, while the third Cu atom, located on a centre of inversion, bridges these two units between two keto O atoms, with two Cl atoms completing a four-coordinate square-planar geometry. The long C₁₁ tails on the macrocycle create well ordered multilayer packing.
