WebMar 7, 2024 · Ruthenocene 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. WebThere are four Ru (C/sub 5/H/sub 5/)/sub 2/ molecules per unit cell. The ruthenium atoms form approximately a face-centered lattice, and the cyclopentadienyl rings lie in an eclipsed configuration with respect to each other about each ruthenium atom. The structure was refined by Fourier and least-squares methods with 791 independent refiections. princeton beats arizona
