Crystal and magnetic structure of CeVO3

Philip Pattison

The crystal structure and the magnetic ordering pattern of the electrically insulating perovskite CeVO3 was investigated by high-resolution powder X-ray diffraction and single-crystal neutron diffraction. A structural phase transition from an orthorhombic ...

A structural investigation of the four phases of 7-oxabicyclo[2.2.1]heptane

Philip Pattison

Powder synchrotron X-ray diffraction studies confirm that 7-oxabicyclo[2.2.1]heptane, (oxanorbornane), forms three solid phases on cooling and four on warming, as previously indicated by spectroscopic and DSC meas urements. The two highest temperature phas ...

Large, heterometallic coordination cages based on ditopic metallo-ligands with 3-pyridyl donor groups

Rosario Scopelliti, Kay Severin, Philip Pattison, Euro Solari, Matthew David Wise

Ditopic N-donor ligands with terminal 4-pyridyl groups are omnipresent in coordination-based self-assembly. The utilization of ligands with 3-pyridyl donor groups is significantly less common, because the intrinsic conformational flexibility of these ligan ...

Thermal decomposition of AlH3 studied by in situ synchrotron X-ray diffraction and thermal desorption spectroscopy

Philip Pattison

The thermal decomposition of alane was investigated by application of synchrotron X-ray diffraction (SR-XRD) and thermal desorption spectroscopy (TDS). Two polymorphs were studied, α- and γ-AlH3. Activation energies, anisotropic volume expansions, and phas ...

The luminescence of NaxEu3+(2−x)/3MoO4 scheelites depends on the number of Eu-clusters occurring in their incommensurately modulated structure

Gervais Chapuis, Jean-Claude Bünzli, Philip Pattison, Alla Arakcheeva, Svetlana Eliseeva

Scheelite related compounds with general formula Mn(XO4)m are of interest owing to their optical properties, stability and relatively simple preparation. Eu3+-containing scheelites are considered as red emitting phosphors and the main factors affecting the ...

Bunch mode specific rate corrections for PILATUS3 detectors

Philip Pattison

PILATUS X-ray detectors are in operation at many synchrotron beamlines around the world. This article reports on the characterization of the new PILATUS3 detector generation at high count rates. As for all counting detectors, the measured intensities have ...

Determination of the molecular structure of the short-lived light-induced high-spin state in the spin-crossover compound [Fe(6-mepy)(3)tren](PF6)(2)

Philip Pattison

In the spin-crossover compound Fe(6-mepy)(3)tren(2), (6-mepy)(3)tren=tris{4-[(6-methyl)-2-pyridyl]-3-aza-butenyl}amine, the high-spin state can be populated as a metastable state below the thermal transition temperature via irradiation into the meta ...

Structural Investigation of the High Spin -> Low Spin Relaxation Dynamics of the Porous Coordination Network [Fe(pz)Pt(CN)(4)]center dot 2.6H(2)O

Philip Pattison

The Hoffman-type coordination compound [Fe(pz)Pt(CN)(4)]2.6H(2)O (pz=pyrazine) shows a cooperative thermal spin transition at around 270K. Synchrotron powder X-Ray diffraction studies reveal that a quantitative photoinduced conversion from the low-spin (LS ...

Neutral Aminyl Radicals Derived from Azoimidazolium Dyes

Rosario Scopelliti, Kay Severin, Henrik Moodysson Rønnow, Philip Pattison, Matthew Wodrich, Ivica Zivkovic, Andrzej Sienkiewicz, Euro Solari, Léonard Yannick Maurice Eymann, Alexander Tskhovrebov, Laurent Alexis Clément Vannay, José Luis Bila

The synthesis and characterization of a new class of neutral aminyl radicals is reported. Monoradicals were obtained by reduction of azoimidazolium dyes with potassium. Structural, spectroscopic, and computational data suggest that the spin density is cent ...

Preparation, crystallographic characterization and theoretical study of C70(CF3)16 and C70(CF3)18

Philip Pattison

C70(CF3)16 and C70(CF3)18, the first trifluoromethylated fullerene derivatives to comprise a pair of adjacent CF3 groups, have been isolated from a mixture obtained via reaction of C70 with CF3I, characterized in a single crystal XRD study and theoreticall ...

Bulk homochirality of a 3-D inorganic framework: ligand control of inorganic network chirality

Philip Pattison

Enantioselective synthesis of a 3-D inorganic net has been achieved leading to metal–organic frameworks built from cobalt-oxide helices in which handedness is controlled by the chirality of the linked ligand. ...

The Intricate Structural Chemistry of MII2nLn-Type Assemblies

Rosario Scopelliti, Kay Severin, Farzaneh Fadaei Tirani, Philip Pattison, Euro Solari, Giacomo Cecot, Mathieu Jérémie Marmier

The reaction of cis-blocked, square-planar MII complexes with tetratopic N-donor ligands is known to give metallasupramolecular assemblies of the formula M2nLn. These assemblies typically adopt barrel-like structures, with the ligands paneling the sides of ...

Structure of 1,4,10,19,25,41-C70(CF3)6, isomer with unique arrangement of addends

Philip Pattison

A novel isomer of C70(CF3)6 has been isolated by HPLC from a mixture prepared by trifluoromethylation of C70 with CF3COOAg. The X-ray structure revealed an unprecedented arrangement of CF3 groups forming a p3mp ribbon. This result provides additional evide ...

A new polymorph of dicesium tetracyanoplatinate monohydrate with unusual platinum stacking

Philip Pattison

We wish to report the discovery of a new and unexpected polymorph of dicesium tetracyanoplatinate. Short, linear chains of five platinum atoms (platinum “needles”) appear in a zigzag arrangement, interspersed by isolated tetracyanoplatinate ions. ...

Persistent Bidirectional Optical Switching in the 2D High-Spin Polymer {[Fe(bbtr)3](BF4)2}∞

Philip Pattison

In the covalently linked 2D coordination network {Fe(bbtr)32}∞, bbtr = 1,4-di(1,2,3-triazol-1-yl)butane, the iron(II) centers stay in the high-spin (HS) state down to 10 K. They can, however, be quantitatively converted to the low-spin (LS) state by ...
