    • Distortion isomerism in ferrous thiourea complexes-II(1) thermodynamics and kinetics 
      Latorre, R.; Costamagna, J.; Frank, E.; Abeledo, C.; Frankel, R. (1979)
      Mössbauer spectroscopy as a function of temperature of Fe(II)(N,N′-dicyclohexyl-thiourea)6(ClO4)2(FeDCTU) shows the existence of two isomeric forms A and B which coexist in the temperature range 200 < T < 300 K. The relative ...
