Crystal structure of -bis-[2-(1-benzotriazol-1-yl)acetato-κ]bis-(ethano-lamine-κ ,)copper(II).

The reaction of 2-(1-benzotriazol-1-yl)acetic acid (HBTA; CHNO) and mono-ethano-lamine (MEA; CHNO) with CuCl·2HO resulted in the formation of the title complex, [Cu(CHNO)(CHNO)] or [Cu(BTA)(MEA)]. Its asymmetric unit comprises one BTA anion coordin-ating to the Cu cation (site symmetry ) through the carboxyl O atom, and one MEA ligand chelating the metal cation by two heteroatoms (O and N). The equatorial Cu-O and Cu-N bond lengths are similar at 2.
