Single-crystal and synchrotron x-ray powder diffraction study of the one-dimensial orthorhombic polymer phase of C[sub 60}.
The 1D-orthorhombic polymer phase of C{sub 60} was originally mentioned in 1995. The present work provides the first direct experimental quantitative evidences of the 1D-polymer chains, clearly seen by single-crystal diffraction. Geometrical details of the [2+2]-cycloaddition rings are compared with those of C{sub 60} dimers and 2D-polymers. Another key structural parameter is the angle of rotation {Psi} of the 1D chains about the polymerization axis. Single-crystal diffraction yields {Psi} {approx} 78{sup o}, whereas accurate synchrotron powder diffraction independently produces a similar {Psi} {approx} 73{sup o}. These values are in qualitative agreement with a former theoretical prediction ({Psi} {approx} 61{sup o}).
