Abstract
Crystal structures of newly synthesized tetramethylammonium hexafluoridoniobate(V) and hexafluoridotantalate(V) (CH3)4N[МF6] (M=Nb, Ta) have been determined; they crystallize in the tetragonal crystal system, sp. gr. P4/nmm. Crystal structures of isostructural compounds (CH3)4N[МF6] (M=Nb, Ta) are formed by virtually regular tetrahedral tetramethylammonium cations (CH3)4N+ (NMe4, TMA) and octahedral complex anions [МF6]– (M=Nb, Ta), fluorine atoms of the equatorial plane are statistically disordered over two positions. Ionic interactions and weak hydrogen bonds C–H•••F join the cations and the complex anions in a 3D assembly.
