Unprecedented lattice volume expansion on doping stereochemically active Pb2+ into uniaxially strained structure of CaBa1−x Pb x Zn2Ga2O7

Unprecedented lattice volume expansion on doping stereochemically active Pb2+ into uniaxially strained structure of CaBa1−x Pb x Zn2Ga2O7

Lone pair cations can impart interesting features in some structures, such as noncentrosymmetry. Here the authors show unexpected cell volume expansion in a polar “114”-type oxide upon replacing Ba2+ with a smaller Pb2+, and attribute it to high stereochemical activity of Pb2+ with the strained fram...
