catena-Poly[[[aqua(glycine-κO)lithium]-μ-glycine-κ2O:O′] bromide]

In the title coordination polymer, {[Li(C2H5NO2)2(H2O)]Br}n, the Li+ cation is coordinated by three carboxylate O atoms of zwitterionic glycine molecules and by a water molecule, forming a distorted tetrahedral geometry. One of the two glycine molecules bridges neighbouring complexes, forming an infinite chain parallel to the c axis. Polymeric chains are further linked by extensive hydrogen bonds involving the Br anions and glycine and water molecules, producing a three-dimensional network.
