Lone pair cations like Pb<sup>2+</sup> are extensively utilized to modify and tune physical properties, such as nonlinear optical property and ferroelectricity, of some specific structures owing to their preference to adopt a local distorted coordination environment. Here we report that the incorporation of Pb<sup>2+</sup> into the polar "114"-type structure of CaBaZn<sub>2</sub>Ga<sub>2</sub>O<sub>7</sub> leads to an unexpected cell volume expansion of CaBa<sub>1-x</sub>Pb<sub>x</sub>Zn<sub>2</ ...[more]
