In the title salt, {[Li(C2H5NO2)(2)]ClO4}(n), the Li+ cation is coordinated by four carboxylate oxygen atoms of the glycine molecules with a distorted tetrahedral geometry. The glycine exists in a zwitterionic form with protonated amino and deprotonated carboxylate groups. In the crystalline state, the title salt is primarily stabilized by intermolecular N-H center dot center dot center dot O and C-alpha-H center dot center dot center dot O interactions which interconnect various units. Hirshfeld surface analysis indicates that the intermolecular H center dot center dot center dot O/O center dot center dot center dot H interactions are the most important contributors to the crystal packing.
