title: Vanadate garnet, Ca2NaMg2V3O12.
abstract: The vanadate garnet Ca(2)NaMg(2)V(3)O(12) (dicalcium sodium dimagnesium trivanadium dodecaoxide), synthesized by a floating zone method, has a notable structural feature in that the dodecahedral-dodecahedral shared edge length is longer than the unshared dodecahedral edge length. It is also noteworthy that the octahedral-dodecahedral shared edge length is as long as the unshared octahedral edge length. These unusual structural features are closely related to the weak repulsions between dodecahedral cations and between dodecahedral and octahedral cations.
