A New Organically Templated Noncentrosymmetric Bismuth Chloride: Synthesis,Structure,and Characterization of[N(CH3)2H2][(CH3)2NH(CH2)2NH(CH3)2][BiCl6]

摘要

Since a wide variety of materials either observed in nature or synthesized by chemists exhibit a marked preference to symmetry,it is quite difficult to find asymmetric substances.Nonetheless,discovering noncentrosymmetric(NCS)materials is a continuing challenge in inorganic solid-state materials chemistry field.This is mainly because acentric materials can reveal extremely important physical properties such as dielectric behavior,ferroelectricity,piezoelectricity,pyro-electricity,and nonlinear optical(NLO)properties.
