Structural integrity transition temperature shift

This also favours the occurrence of temperature-dependent disorder. Computer simulation of structural variations and comparison of both theoretical and experimental behaviour of the integral intensities of structure-sensitive diffraction reflections allow one to prove the presence of the temperature-dependent disorder of the Fe(C12Gm)3(B i-C4H9)2 molecules in crystals. The thermal expansion anomalies and the relative shift of the molecules preced the phase transition and, presumably, promot its realization in this crystal [282].
