R., Heiney, Paul A., Stephens, Peter W., Dinnebier, R. E., Zhu, Q., McGhie, Andrew R., Strongin, Robert M., Brandt, B. M., Smith, Amos B., III Year: 2000 We have used x-ray powder diffraction and differential scanning calorimetry to study the crystalline structures and thermal behavior of the 6,6-cyclopropane isomer of C61H2. At room temperature, the C61H2 cyclopropane molecules, like those of the 6,5-annulene isomer and C60O epoxide, are orientationally disordered and crystallize on a face-centered-cubic lattice such that their methylene groups are statistically disordered among the octahedral voids. Unlike 6,5−C61H2 and C60O, the low-temperature structure is not Pa3¯, but rather a low-symmetry orthorhombic lattice in which a≈b Title: Structure and Phase Transitions of the 6, 6-Cyclopropane Isomer of C_ {61} H_ {2} Author: Stetzer, M.
