摘要
Light blue single crystals of [Fe(NH3)(6)][TaF6](2) and [Ni(NH3)(6)][TaF6](2) are obtained from 36:1:6 molar mixtures of (NH4)F, iron/nickel and tantalum powders, respectively, in sealed Monel metal ampoules at 400 degrees C. They both crystallize isotypic with [CO(NH3)(6)][PF6](2) (cubic, Fm-3m, Z = 4, a = 1259.0(2)/1260.4(2) pm) in a structure that can be derived from the basic fluorite-type of structure according to [Ca][F](2)=[Fe(NH3)(6)] [TaF6](2), for example.
