One-dimensional composite host-guest structure in BaVS3

László Forró, Gervais Chapuis, Alla Arakcheeva, Helmuth Berger, Philip Pattison, Neven Barisic

A detailed synchrotron X-ray diffraction (XRD) study performed with a single crystal of BaVS3 (barium vanadium trisulfide) in the temperature range between 10 and 295 K is reported. Aside from the known tetragonal–orthorhombic (240 K) and orthorhombic–mono ...

Zero-dimensional hybrid iodobismuthate derivatives: from structure study to photovoltaic application

Mohammad Khaja Nazeeruddin, Yi Zhang, Kurt Schenk, Farzaneh Fadaei Tirani, Philip Pattison, Peng Gao

The quest for lead-free light-absorbing perovskite materials has long been the target of researchers to make the 'star' material friendly to the commercial market. After a summary of different lead-free solar absorbers, we demonstrate a zero-dimensional io ...

Chirok: a post-refinement tool to analyse absolute structure

Philip Pattison

Chirok is software for a post-refinement test of the absolute structure. The software allows a user to calculate a distribution of the measure of chirality based on intensity quotients and linked to the Flack parameter. The distribution is fitted by a set ...

The influence of the incommensurately modulated structure on the physical properties of Fe1.35Ge

László Forró, Alla Arakcheeva, Helmuth Berger, Philip Pattison, Krunoslav Prsa, Andrea Pisoni, Sergiy Katrych, Jacim Jacimovic

Single crystal growth by chemical vapour transport has resulted samples with Fe1.35Ge stoichiometry. Structural study has shown that the large number of vacancies introduces an incommensuately modulated structure. The electrical resistivity is in the 200 m ...

Reentrant magnetism at the borderline between long-range antiferromagnetic order and spin-glass behavior in the B-site disordered perovskite system Ca2-x SrxFeRuO6

Philip Pattison

We report on the coexistence of magnetic order and disorder in the atomically disordered double perovskites Ca2FeRuO6 and CaSrFeRuO6. Powder x-ray and neutron diffraction were used to investigate the crystal structure and magnetic ordering of these oxides. ...

High-Temperature Ferrimagnetism with Large Coercivity and Exchange Bias in the Partially Ordered 3d/5d Hexagonal Perovskite Ba2Fe1.12Os0.88O6

Philip Pattison

Double perovskite oxides A(2)BB'O-6 combining 3d and 4d or 5d transition metal ions at the B and B' sites feature a variety of magnetic and magneto-electric properties. Targeting Ba2FeOsO6, we synthesized powder samples of nonstoichiometric Ba2Fe1.12Os0.88 ...

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 ...

Incommensurate atomic density waves in the high-pressure IVb phase of barium

Gervais Chapuis, Alla Arakcheeva, Philip Pattison, Vladimir Dmitriev

The host–guest structures of elements at high pressure discovered a decade ago still leave many open questions due to the lack of precise models based on full exploitation of the diffraction data. This concerns in particular Ba IV, which is stable in the r ...

Spin and orbital disordering by hole doping in Pr1-xCaxVO3

Philip Pattison

High-resolution powder x-ray diffraction and single-crystal neutron diffraction were used to investigate the crystal structure and magnetic ordering of the compound Pr1-xCax VO3 (0

The Ligand Aspect Ratio as a Decisive Factor for the Self-Assembly of Coordination Cages

Rosario Scopelliti, Kay Severin, Philip Pattison, Euro Solari, Konstantin Zhurov, Suzanne Maria Jansze, Giacomo Cecot, Matthew David Wise, Alba Finelli

It is possible to control the geometry and the composition of metallasupramolecular assemblies via the aspect ratio of their ligands. This point is demonstrated for a series of iron- and palladium-based coordination cages. Functionalized clathrochelate com ...
