Crystal structure and Hirshfeld surface analysis of poly[[di-μ3-glycine-lithium] perchlorate]

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⋯O and Cα—H⋯O inter­actions which inter­connect various units. Hirshfeld surface analysis indicates that the inter­molecular H⋯O/O⋯H inter­actions are the most important contributors to the crystal packing.
