WebRuthenocene can be isothermally compressed in its ambient-pressure phase α up to 3.9 GPa, when it transforms to the new phase, β. The transition between phases α and β proceeds with an exceptionally wide hysteresis extending between 0.7 and 3.9 GPa. The transition destroys single crystals of RuCp 2 Web《Journal of Molecular Structure》2003年第1a2期共发表53篇文献，掌桥科研收录1995年以来所有《Journal of Molecular Structure》期刊内所有文献， ISSN为0022-2860，
