Crystal structure and Hirshfeld surface analysis of tri-chlorido-(1,10-phenanthroline-κ ,')phenyltin(IV).

The title compound, [Sn(CH)Cl(CHN)], which was obtained by the reaction between 1,10-phenanthroline and phenyl-tin trichloride in methanol, exhibits intra-molecular hydrogen-bonding inter-actions involving the chlorine and hydrogen atoms. Crystal cohesion is ensured by inter-molecular C-H⋯Cl hydrogen bonds, as well as -⋯π and π-stacking inter-actions involving three different aromatic rings with centroid-centroid distances of 3.6605 (13), 3.

Bis(2-carb-oxy-quinolinium) hexa-chlorido-stan-nate(IV) dihydrate.

In the hydrated title salt, (CHNO)[SnCl]·2HO, the tin(IV) atom is located about a center of inversion. In the crystal structure, the organic cation, the octa-hedral inorganic anion and the water mol-ecule of crystallization inter-act through O-H⋯O, N-H⋯O and O-H⋯Cl hydrogen bonds, supplemented by weak π-π stacking between neighboring cations, and C-Cl⋯π inter-actions.

Synthesis, crystal structure and Hirshfeld surface of bis-(2-amino-pyridinium) hexa-chlorido-stannate(IV).

In the title mol-ecular salt, (CHN)[SnCl], the cation is protonated at the pyridine N atom and the complete dianion is generated by a crystallographic centre of symmetry. In the crystal, N-H⋯Cl hydrogen bonds link the components into a three-dimensional network built up from the stacking of alternate cationic and anionic layers. The nature of the inter-molecular inter-actions has been analysed in terms of the Hirshfeld surfaces of the cations and the anions.

Temporal Resolution Multiplexing: Exploiting the limitations of spatio-temporal vision for more efficient VR rendering.

Rendering in virtual reality (VR) requires substantial computational power to generate 90 frames per second at high resolution with good-quality antialiasing. The video data sent to a VR headset requires high bandwidth, achievable only on dedicated links. In this paper we explain how rendering requirements and transmission bandwidth can be reduced using a conceptually simple technique that integrates well with existing rendering pipelines.

Crystal structure of poly[di-aqua-(μ-2-carb-oxy-acetato-κ(3) O,O':O'')(2-carb-oxy-acetato-κO)di-μ-chlorido-dicobalt(II)].

The asymmetric unit of the title polymer, [Co2(C3H3O4)2Cl2(H2O)2] n , comprises one Co(II) atom, one water mol-ecule, one singly deprotonated malonic acid mol-ecule (HMal(-); systematic name 2-carb-oxy-acetate) and one Cl(-) anion. The Co(II) atom is octa-hedrally coordinated by the O atom of a water mol-ecule, by one terminally bound carboxyl-ate O atom of an HMal(-) anion and by two O atoms of a chelating HMal(-) anion, as well as by two Cl(-) anions. The Cl(-) anions bridge two Co(II) atoms, forming a centrosymmetric Co2Cl2 core.
