AB  - We report a synthetic and theoretical study of the solid solution Sn(x)Fe(4-x)N 
      (0 </= x </= 0.9). A previously published ammonolytic synthesis was successfully 
      modified to achieve the metastable nitrides in phase-pure quality out of many 
      competing phases. As TG-DSC measurements show, the thermal stability of the 
      nitrides increases with increasing tin content. The Sn(x)Fe(4-x)N series of 
      compounds adopts an antiperovskite-like structure in space group Pm3̅m. Various 
      experimental and theoretical methods provide evidence that the iron substitution 
      by tin exclusively takes place at Wyckoff position 1a and leads to a Vegard-type 
      behavior of the lattice parameter over the compositional range, with an expection 
      for a small internal miscibility gap around Sn(0.33)Fe(3.67)N of unknown cause. 
      For highly tin-substituted iron nitrides the composition was clarified by prompt 
      gamma-ray activation analysis (PGAA) and determined as 
      Sn(0.78(3))Fe(3.22(4))N(0.95(3)) evidencing a fully occupied nitrogen position. 
      Magnetic measurements reveal a linear weakening of ferromagnetic interactions 
      with increasing tin concentration.
