I11-High Resolution Powder Diffraction	Structure and magnetism of the A site scandium perovskite (Sc0.94Mn0.06)Mn0.65Ni0.35O3 synthesized at high pressure Chris I. Thomas , Matthew Suchomel , Giap V. Duong , Andrew Fogg , John Claridge , Matthew Rosseinsky Philosophical Transactions Of The Royal Society A: Mathematical, Physical And Engineering Sciences 372 (2013), 20130012 - 20130012 DOI: 10.1098/rsta.2013.0012 PMID: 24615150 Show Abstract ▼ Abstract: Scandium perovskite (Sc0.94Mn0.06)Mn0.65Ni0.35O3, synthesized at high pressure and high temperature, has a triclinic structure (space group ) at room temperature and ambient pressure with a ?2ap×?2ap×2ap structure with ??90°,??89°,??90°. Magnetic measurements show that the material displays Curie–Weiss behaviour above 50?K with C=2.11?emu?K?mol?1 (?eff=4.11??B per formula unit) and ?=?95.27?K. Bond valence sum analysis of the crystal structure shows that manganese is present in three different oxidation states (+2, +3, +4), with the +2 oxidation state on the A site resulting in a highly tilted perovskite structure (average tilt 21.2° compared with 15.7° calculated for LaCaMnNbO6), giving the formula .

I19-Small Molecule Single Crystal Diffraction	Synthesis and characterisation of a new anion exchangeable layered hydroxyiodide Faye Y. Southworth , Claire Wilson , Simon J. Coles , Andrew M. Fogg Dalton Transactions 43 (27), 10451-10455 DOI: 10.1039/c4dt00123k Diamond Proposal Number(s): [6916] Show Abstract ▼ Abstract: Lu4O(OH)9I·3H2O is a new member of the anion exchangeable lanthanide hydroxyanion family of materials which has been synthesised hydrothermally. Its structure comprises positively charged [Lu4O(OH)9(H2O)3]+ layers with exchangeable charge balancing iodide anions located in the interlayer gallery. It has been found to undergo facile anion exchange reactions with dicarboxylate anions such as succinate and terephthalate at room temperature but reacts less readily with disulfonate anions such as 1,5- and 2,6-naphthalenedisulfonate under the same conditions. At reaction temperatures above 200 °C the cationic inorganic framework Lu3O(OH)6I·2H2O forms instead of the layered phase.	Feb 2014
I19-Small Molecule Single Crystal Diffraction	Yb3O(OH)6Cl.2H2O: an anion-exchangeable hydroxide with a cationic inroganic framework structure Helen V. Goulding , Sarah E. Hulse , William Clegg , Ross W. Harrington , Helen Y. Playford , Richard I. Walton , Andrew M. Fogg Journal Of The American Chemical Society 132 (39), 13618-13620 DOI: 10.1021/ja104636x PMID: 20614886 Diamond Proposal Number(s): [987] Show Abstract ▼ Abstract: The first anion-exchangeable framework hydroxide, Yb3O(OH)(6)Cl center dot 2H(2)O, has been synthesized hydrothermally. This material has a three-dimensional cationic ytterbium oxyhydroxide framework with one-dimensional channels running through the structure in which the chloride anions and water molecules are located. The framework is thermally stable below 200 degrees C and can be reversibly dehydrated and rehydrated with no loss of crystallinity. Additionally, it is able to undergo anion-exchange reactions with small ions such as carbonate, oxalate, and succinate with retention of the framework structure.	Oct 2010
