At low temperatures the compound crystallizes in space group P1̅ with one ordered complex molecule in general position. Results derived from an intensity data set collected at 120 K are reported. Above the phase transition at 207 K both the cell metric and the symmetry of the diffraction pattern allow the transformation to a centered monoclinic unit cell in space group C2/c. In this high temperature phase the molecule is located on a twofold crystallographic axis and shows disorder with respect to the orientation of the vinyl substituent. The crystal and molecular structure based on a data collection at 293 K is described. © 2003 Oldenbourg Wissenschaftsverlag GmbH Crystallography nationallicence Inorganic chemistry nationallicence Organic chemistry nationallicence Hu Chunhua aut Huster Jürgen aut Englert Ullrich aut Zeitschrift für Kristallographie - Crystalline Materials De Gruyter Oldenbourg 218/11(2003-11-01), 761-765 2194-4946 218:11<761 2003 218 zkri https://doi.org/10.1524/zkri.218.11.761.20299 text/html Onlinezugriff via DOI 1 research article jats NATIONALLICENCE 856 40 https://doi.org/10.1524/zkri.218.11.761.20299 text/html Onlinezugriff via DOI NATIONALLICENCE 700 1- Hu Chunhua aut NATIONALLICENCE 700 1- Huster Jürgen aut NATIONALLICENCE 700 1- Englert Ullrich aut NATIONALLICENCE 773 0- Zeitschrift für Kristallographie - Crystalline Materials De Gruyter Oldenbourg 218/11(2003-11-01), 761-765 2194-4946 218:11<761 2003 218 zkri CC0 http://creativecommons.org/publicdomain/zero/1.0 nationallicence BK010053 XK010053 XK010000 NATIONALLICENCE NATIONALLICENCE NL-gruyter
