AB  - The crystal structure of the low-temperature garnet-like form of trisodium 
      diiron(III) triarsenate, Na(3)Fe(2)(AsO(4))(3), exhibits a three-dimensional 
      framework with small tunnels running along the [111] direction, in which the 
      Na(+) cations are located. This study demonstrates the structural origins of the 
      different ionic conductivities of the low- and high-temperature forms. Sodium 
      conduction properties are simulated by means of the bond-valence-sum (BVS) model; 
      the correlations between the low- and high-temperature crystal structures are 
      discussed. The As, Fe and Na atoms lie on special positions (Wyckoff symbols 24d, 
      16a and 24c, respectively).
