The {N(C 2 H 5 ) 4 } 2 [UF 6 ] · 2H 2 O ( 1 ), {N(C 2 H 5 ) 4 } 2 [HfF 6 ] · 2H 2 O ( 2 ), and {N(C 2 H 5 ) 4 } 2 [CeF 6 ] · 6H 2 O ( 3 ) salts were prepared in high yield (ca. 80 %) from the reaction of M F 4 with tetraethylammonium fluoride in propylene carbonate and for the first time their solid‐state structures characterized by single‐crystal X‐ray diffraction. The compounds 1 , 2 and 3 crystallize in the space groups Pcca, P 2 1 / n 1 and Pca 2 1 , respectively. In 1 , 2 , and 3 the M F 6 2– anions are almost octahedral with average M –F distances of 2.16, 1.999, and 2.148 Å.
