DOIAbstract
For a very long time, Ba<sub>16</sub>Ga<sub>32</sub>Sn<sub>104</sub> has been the sole representative of tin clathrates with the type II structure. Herein, we present several new members of this structural family: Cs<sub>8</sub>Ba<sub>16</sub>Ga<sub>39.7(3)</sub>Sn<sub>96.3(3)</sub>, Rb<sub>9.9(5)</sub>Ba<sub>13.3(2)</sub>Ga<sub>36.4(3)</sub>Sn<sub>99.6(3)</sub>, and K<sub>2.0(4)</sub>Ba<sub>14.0(4)</sub>Ga<sub>30.4(2)</sub>Sn<sub>105.6(4)</sub>. The successful synthesis of these novel compounds was facilitated through the use of alkali and alkaline-earth metals, which selectively fill the available cages
