Abstract: The new Zintl compounds RbNa₈Ga₃Pn₆ (Pn = P, As) and Na₁₀NbGaAs₆ have been synthesized from the corresponding elements at high temperatures. RbNa₈Ga₃P₆ and RbNa₈Ga₃As₆ crystallize with a novel structure type that features trigonal planar [Ga₃P₆]^9– and [Ga₃As₆]^9– motifs, which are isosteric with the 1,3,5-trioxanetrione (a cyclic trimer of carbon dioxide). Na₁₀NbGaAs₆, an unforeseen side product of the same reactions boasts a structure, which is based on NbAs₄ and GaAs₄ tetrahedra, condensed by sharing common edges into [NbGaAs₆]^10– dimers. The bonding characteristics of both structures are discussed. All three compounds reported herein represent the first compounds found in the respective quaternary systems.
