catena-Poly[copper(II)-mu-L-tyrosyl-L-leucinato]

Abstract

In the title compound, [Cu(C15H20N2O4)](n), the copper(II) coordination is square planar. The anionic L-tyrosyl-L-leucinate ligand binds in an N,N',O-tridentate mode to one Cull cation on one side and in an O-monodentate mode to a second Cull cation on the other side, thus defining -Cu-O-C-O-Cu'-chains which run along the a axis. These chains are held together by a strong hydrogen bond involving the hydroxy H atom.
