N¹⁴ occurs at 3.34 MC at H₀ = 10600 G
in K₃Co(CN)₆. Search for N¹⁴ in Na₃Co(NO₂)₆ in
freq range 3.445 MC - 3.26 MC is negative

NaSbF₆ is cubic a = 8.18 Å The structure is
probably the space group
4 Na in 4(b) , 4 Sb in 4(a), 24 F in 24(d) ;
x = -0.05, y = -0.05 , z = 0.225

within the SbF₆^- octahedron 2.67, 2.78
and from octahedron [?] octahedron 2.72 Å
