Abstract
The volatile Fe(dpm)3 complex was studied by X-ray diffraction at 243 K and 210 K. A phase transition from monoclinic to triclinic structure was found in the temperature range 236-226 K. The packing of complexes in the structures is analyzed by the procedure of translation sublattice isolation. The motif of mutual arrangement of Fe atoms is pseudohexagonal in both modifications. Apart from the differences in the Fe…Fe distances, there are differences in rotation of definite chelate rings.
