“…Structural distortions can be induced by alternating different tetrahedra and/or by the insertion of large monovalent cations in the cavities of these structures. So, numerous stuffed cristobalite-type compounds of general formula A I 2 B II X IV O 4 (A I ¼ Na, K, Rb, Cs; B II ¼ Zn, Mg, Cd; X IV ¼ Si, Ge, Ti) have been obtained [2][3][4][5][6][7]. * This study, concerning K 2 ZnGeO 4 , is intended to establish correlations between crystal structures and ferroic properties of oxide compounds.…”

K 2 ZnGeO 4 belongs to the 'stuffed' cristobalite structural type. The -form (SG Pca2 1 ) changes to -form (SG F 43m) above 1049 K by a displacive/rotational transformation with ferroelectric/ferroelastic character, in which the strain is only coupled with the order parameter. The distortion leading from -HT to -LT form results from important strains and geared rotations of the ZnO 4 and GeO 4 tetrahedra. The broad permittivity peak around the transition temperature is typical of a first-order transition. A comparison with isotypic compounds shows that the covalency of the structural skeleton plays a major role in the transition phenomenon.
