Lithium iron arsenide phases with compositions close to LiFeAs exhibit superconductivity at temperatures at least as high as 16 K, demonstrating that superconducting [FeAs](-) anionic layers with the anti-PbO structure type occur in at least three different structure types and with a wide range of As-Fe-As bond angles. 
Structure, antiferromagnetism and superconductivity of the layered iron arsenide NaFeAs.

Phase separation and superconductivity in Fe(1+x)Te(0.5)Se(0.5).
TLDR
It is shown that the superconducting state is controlled by the stacking of its anti-PbO layers, such that homogeneous ordering hinders superconductivity and the highest volume fractions are observed in phase separated structures as evidenced by either a distribution of lattice parameters or microstrain.

TLDR
The ternary iron arsenide BaFe2As2 becomes superconducting by hole doping, which was achieved by partial substitution of the barium site with potassium by substituting Ba2+ for K+ ions, and this class of superconductors by oxygen-free compounds with the ThCr2Si2-type structure was expanded. Expand
