This compound, [Fe<jats:sub>2<\/jats:sub>(ddpp)<jats:sub>2<\/jats:sub>(NCS)<jats:sub>4<\/jats:sub>]<jats:bold>\u22c5<\/jats:bold>4\u2009CH<jats:sub>2<\/jats:sub>Cl<jats:sub>2<\/jats:sub>, undergoes a two\u2010step full spin crossover. Structural analysis at each of the three plateau temperatures has revealed a dinuclear molecule with spin states HS\u2013HS, HS\u2013LS and LS\u2013LS (HS: high spin, LS: low spin) for the two iron(II) centres. This is the first time that resolution of the metal centres in a HS\u2013LS ordered state has been achieved in a two\u2010step dinuclear iron(II) spin\u2010crossover compound. Thermogravimetric data show that the dichloromethane solvate molecules can be removed in two distinct steps at 120\u2009\u00b0C and 200\u2009\u00b0C. The partially de\u2010solvated clathrate, [Fe<jats:sub>2<\/jats:sub>(ddpp)<jats:sub>2<\/jats:sub>(NCS)<jats:sub>4<\/jats:sub>]<jats:bold>\u22c5<\/jats:bold>CH<jats:sub>2<\/jats:sub>Cl<jats:sub>2<\/jats:sub>, undergoes a one\u2010step transition with an increased transition temperature with respect to the as synthesised material. Structural characterisation of this material reveals subtle changes to the coordination geometries at each of the iron(II) centres and striking changes to the local environment of the dinuclear complex. The fully de\u2010solvated material remains high spin over all temperatures. Interestingly, the solvent can be re\u2010introduced into the monosolvated solid to achieve complete conversion back to the original two\u2010step crossover material, [Fe<jats:sub>2<\/jats:sub>(ddpp)<jats:sub>2<\/jats:sub>(NCS)<jats:sub>4<\/jats:sub>]<jats:bold>\u22c5<\/jats:bold>4\u2009CH<jats:sub>2<\/jats:sub>Cl<jats:sub>2<\/jats:sub>.<\/jats:p>","DOI":"10.1002\/chem.200601069","type":"journal-article","created":{"date-parts":[[2006,10,6]],"date-time":"2006-10-06T07:01:50Z","timestamp":1160118110000},"page":"8220-8227","source":"Crossref","is-referenced-by-count":110,"title":["Structural and Magnetic Resolution of a Two\u2010Step Full Spin\u2010Crossover Transition in a Dinuclear Iron(II) Pyridyl\u2010Bridged Compound"],"prefix":"10.1002","volume":"12","author":[{"given":"Jarrod J.
