2.1) The nearest neighbor Ga atoms are at 
(-a/4, a/4, -a/4), (-a/4, -a/4, a/4), (a/4, -a/4, -a/4), and (a/4, a/4, a/4). 
The distance 31/2 a/4 = 0.254 nm. 
The ionic lengths are given as rGa 
+1 ~ 0.081 nm and rAs 
-3 ~ 0.22 nm. Then the sum of the 
ionic distances is slightly larger than the a spacing in the crystal. 
2.2) For the Ga atom at (a/4, a/4, a/4), the for nearest neighbors are at: 
(0, 0, 0), (a/2, a/2, 0), (a/2, 0, a/2) and (0, a/2, a/2). 
They are the As atoms on the faces of the ...
