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

Abstract

In the title salt, {[Li(C2H5NO2)2]ClO4} n , the Li+ cation is coordinated by four carboxyl-ate oxygen atoms of the glycine mol-ecules with a distorted tetra-hedral geometry. The glycine exists in a zwitterionic form with protonated amino and deprotonated carboxyl-ate groups. In the crystalline state, the title salt is primarily stabilized by inter-molecular N-H⋯O and Cα-H⋯O inter-actions which inter-connect various units. Hirshfeld surface analysis indicates that the inter-molecular H⋯O/O⋯H inter-actions are the most important contributors to the crystal packing.
