Since most of the solid-state materials preferred centrosymmetric (CS) structures thermodynamically, introducing chiral molecule on inorganic units is an effective pathway to discover new macroscopic non-centrosymmetric (NCS) structures systematically. New enantiomorphic histidinium tantalum fluoride compounds have been successfully synthesized through slow evaporation method and their structures were determined by single crystal X-ray diffraction (SC-XRD). The structures of the title compounds are composed of L- or D-histidinium cations and distorted monocapped trigonal prismatic tantalum fluoride polyhedra. SC-XRD reveals that the materials crystallized in the polar space group, P21 attributed to the introduced amino acid, histidine. Other characterizations such as spectroscopic, thermal, and elemental analyses will be also provided.
