Poly[di-?-glycinato-copper(II)]: a two-dimensional coordination polymer.

ABSTRACT: The title coordination polymer, [Cu(C(2)H(4)NO(2))(2)](n), is two-dimensional and consists of a distorted octa-hedral copper coordination polyhedron with two bidentate glycine ligands chelating the metal through the O and N atoms in a trans-square-planar configuration. The two axial coordination sites are occupied by carbonyl O atoms of neighbouring glycine mol-ecules. The Cu-O distances for the axial O atoms [2.648?(2) and 2.837?(2)?Å] are considerably longer than both the Cu-O [1.9475?(17) and 1.9483?(18)?Å] and Cu-N [1.988?(2) and 1.948?(2)?Å] distances in the equatorial plane, which indicates a strong Jahn-Teller effect. In the crystal, the two-dimensional networks are arranged parallel to (001) and are linked via N-H?O hydrogen bonds, forming a three-dimensional arrangement.
