Redetermination of K4[Bi2Cl10]·4H2O

چکیده
In comparison with the previous refinement of tetra-potassium di-μ-chlorido-bis-[tetra-chloridobismuthate(III)] tetra-hydrate [Volkova, Udovenko, Levin & Shevchenko (1983). Koord. Khim.9, 356-360], the current redetermination reveals anisotropic displacement parameters for all non-H atoms, localization of the H atoms, and higher precision of lattice parameters and inter-atomic distances. The crystal structure is built up of edge-sharing [Bi(2)Cl(10)](4-) double octa-hedra with the bridging Cl atoms situated on a mirror plane, three K(+) counter-cations (two of which are on mirror planes), and two water mol-ecules that are solely coordinated to the K(+) cations. These building units are linked into a three-dimensional network structure. Additional O-H⋯Cl hydrogen bonds between the water mol-ecules and the complex anions stabilize this arrangement.

Redetermination of the crystal structure of 3,5-dimethylpyrazolium β-octamolybdate tetrahydrate
The title compound, (C5H9N2)4[Mo8O26]·4H2O, was reported previously from a room-temperature data collection from which only the metal atoms could be refined anisotropically [FitzRoy et al. (1989 ▸). Inorg. Chim. Acta, 157, 187-194]. The current redetermination at 180 (2) K models all the non-H atoms with anisotropic displacement parameters and fully describes the supra-molecular N-H⋯O and O-H⋯O...

متن کاملThree Color Ramsey Numbers for Graphs with at most 4 Vertices
For given graphs H1, H2, H3, the 3-color Ramsey number R(H1, H2, H3) is the smallest integer n such that if we arbitrarily color the edges of the complete graph of order n with 3 colors, then it always contains a monochromatic copy of Hi colored with i, for some 1 6 i 6 3. We study the bounds on 3-color Ramsey numbers R(H1, H2, H3), where Hi is an isolate-free graph different from K2 with at mo...
متن کاملA new result on chromaticity of K4-homoemorphs with girth 9
For a graph $G$, let $P(G,lambda)$ denote the chromatic polynomial of $G$. Two graphs $G$ and $H$ are chromatically equivalent if they share the same chromatic polynomial. A graph $G$ is chromatically unique if any graph chromatically equivalent to $G$ is isomorphic to $G$. A $K_4$-homeomorph is a subdivision of the complete graph $K_4$. In this paper, we determine a family of chromatically uni...
