Author(s) from Durham


The crystal structure of the iron(II) spin-crossover compound [Fe(C10H8N6)(2)](ClO4)(2) in the high-spin state has been solved from powder X-ray diffraction data using the DASH program and refined using Rietveld refinement. The thermal spin transition has been monitored by following the change in unit-cell parameters with temperature. The title compound has been found to undergo a crystallographic phase change, involving a doubling of the crystallographic a axis, on undergoing the spin transition.
