Inclusion of molecular ions with additional characteristics, including anisotropic shape, magnetic moments, and bonding, widens the possibilities for controling tuning structure properties extended solids. In contrast to zealous efforts at perovskite ferroelectrics, ferroelectric-like feature antiperovskite containing asymmetrical inorganic polyanion receives less research interest. Here, we report high-pressure synthesis a Na3H(ZnH4) (ZnH4)2– which crystallizes into P4/ncc space group, in...
Abstract Bulachite specimens from Cap Garonne, France, comprise two intimately mixed hydrated aluminium arsenate minerals with the same Al:As ratio of 2:1 and different water contents. The crystal structures both have been solved using data low-dose electron diffraction tomography combined synchrotron powder X-ray diffraction. One has pattern (PXRD) as for published bulachite. It orthorhombic symmetry, space group Pnma unit-cell parameters a = 15.3994(3), b 17.6598(3), c 7.8083(1) Å Z 4,...
There is a wealth of materials that are beam sensitive and only exist in nanometric crystals, because the growth bigger crystals either impossible or so complicated it not reasonable to spend enough time resources grow big before knowing their potential for research applications. This difficulty encountered minerals, zeolites, metal-organic frameworks molecular including pharmaceuticals biological crystals. In order study these structure determination method size needed. The makes them...
<title>Abstract</title> Conventional refinement strategies used for three-dimensional electron diffraction (3D ED) data disregard the bonding effects between atoms in a molecule by assuming pure spherical model called Independent Atom (IAM) and may lead to inaccurate or biased structure. Here we show that it is possible perform going beyond IAM with data. We kappa which models charge transfers while model. demonstrate procedure analysing five inorganic samples; quartz, natrolite, borane,...

Electron crystallography reveals the crystal structures of two metal-radical coordination frameworks with field-induced metamagnetic transition and gives impetus to research on molecule-based magnets.
Structure solution and refinement based on 3D electron diffraction have undergone a spectacular evolution in recent years: not only can we now reliable diffracted intensities, thanks to crucial technological advances such as beam precession or development detectors with single detection, but also process these intensities more finely the of powerful dedicated programs [1-3].The structure complex nanocrystalline compounds is accessible.Today, 3D-ED solve irradiation sensitive compounds,...
The naturally occurring mineral Bulachite, from Neubulach, northern Black Forest, Germany was first described by Walenta (1983).This hydrous aluminum arsenate forms as aggregates of fine white neeedles encrusting quartz and associated with arsenocrandallite, malachite, barium pharmacosiderite goethite.Walenta reported an orthorhombic unit cell, cell parameters a = 15.53,b 17.78, c 7.03 Å chemical composition Al2(AsO4)(OH)3(H2O)3.The sample studied in this work comes the South mine Cap...
