#Niobium Boride, zeta-NbB #Structure Orthorhombic, Cmcm(63), 2=4. The structure was studied by Andersson and Kiessling [1950] #and by Brewer et al., [1951). It is isostructural with CrB. #Lattice constants of this sample #a = 3.2973(4), b = 8.7229(10), c = 3.1663(3) #a/b = 0.3780, c/b = 0.3630 #Volume 91.069 A 3 20.34 28.93 34.97 40.81 41.37 50.78 55.73 58.23 59.95 62.33 63.98 66.30 67.51 71.33 71.73 73.94 78.73 82.73 84.84 88.42 89.89 92.01 96.71
