Crystal structure of anhydrous poly[bis­(μ₂-sarcosinato-κ³O,N:O′)copper(II)]

The copper(II) ion of the anhydrous form of bis­(sarcosinato)copper(II) exhibits a [4 + 2] coordination sphere with four shorter equatorial bonds to the N and carboxyl­ate O atoms of two sarcosinate anions, and two longer axial bonds to O atoms of neighboring complexes, leading to a sheet structure parallel to (001).
