Abstract

A cubane-type Cu4O4 core have been found in the title tetrameric copper(II) complex {tetrakis([mu]-3 bromobenzoato)-1[kappa]O:2[kappa]O';2[kappa]O:3[kappa]O';3[kappa]O:4[kappa]O';4[kappa]O:1[kappa]O'- tetrakis[[mu]-2-(dimethylamino)ethanolato]-1[kappa]N,1:2:3[kappa]3O;2[kappa]N,2:3:4[kappa]3O; 3[kappa]N,3:4:1[kappa]3O;4[kappa]N,4:1:2[kappa]3O-tetracopper(II), [Cu4(C7H4BrO2)4(C4H10NO)4]}. The short Cu-Oethanolato bonds form an eight-membered ring folded in a boat-like conformation. The Cu...Cu distances vary between 3.121 (2) and 3.796 (3) Å. Each Cu atom has a distorted octahedral environment. Two ethanolato O atoms, a carboxyl O atom and an amino N atom form the equatorial coordination plane, with Cu-O bond lengths in the range 1.914 (12)-1.954 (14) Å and Cu-N bond lengths in the range 2.011 (12)-2.057 (13) Å. The axial sites are occupied by an ethanolato O atom and an O atom of the carboxylate group, with Cu-O distances in the range 2.443 (8)-2.877 (9) Å.
