Chiral and Polar Duality Design of Heteroanionic Compounds: Sr₁₈ Ge₉ O₅ S₃₁ Based on [Sr₃ OGeS₃ ]²⁺ and [Sr₃ SGeS₃ ]²⁺ Groups.

ABSTRACT: Chirality and polarity are the two most important and representative symmetry-dependent properties. For polar structures, all the twofold axes perpendicular to the principal axis of symmetry should be removed. For chiral structures, all the mirror-related symmetries and inversion axes should be removed. Especially for duality (polarity and chirality), all of the above symmetries should be broken and that also represents the highest-level challenge. Herein, a new symmetry-breaking strategy that employs heteroanionic groups to construct hourglass-like [Sr₃ OGeS₃ ]²⁺ and [Sr₃ SGeS₃ ]²⁺ groups to design and synthesize a new oxychalcogenide Sr₁₈ Ge₉ O₅ S₃₁ with chiral-polar duality is p
