Na V Ga
NaVGa crystallizes in the trigonal R3m space group. Na(1) is bonded to three equivalent V(1) and four equivalent Ga(1) atoms to form NaV3Ga4 hexagonal pyramids that share corners with three equivalent Ga(1)Na4V3 hexagonal pyramids, corners with six equivalent Na(1)V3Ga4 hexagonal pyramids, edges with three equivalent Ga(1)Na4V3 hexagonal pyramids, and edges with six equivalent Na(1)V3Ga4 hexagonal pyramids. All Na(1)-V(1) bond lengths are 2.69 Å. There are three shorter (2.76 Å) and one longer (3.10 Å) Na(1)-Ga(1) bond length. V(1) is bonded in a hexagonal planar geometry to three equivalent Na(1) and three equivalent Ga(1) atoms. All V(1)-Ga(1) bond lengths are 2.69 Å. Ga(1) is bonded to four equivalent Na(1) and three equivalent V(1) atoms to form GaNa4V3 hexagonal pyramids that share corners with three equivalent Na(1)V3Ga4 hexagonal pyramids, corners with six equivalent Ga(1)Na4V3 hexagonal pyramids, edges with three equivalent Na(1)V3Ga4 hexagonal pyramids, and edges with six equivalent Ga(1)Na4V3 hexagonal pyramids.
