TL;DR: In this paper, it was shown that the far-infrared region can be used as a diagnostic probe in recognizing triiodides in the presence of a triiodide in the P-1 space group.

TL;DR: The crystal structures of two triorganotin butyrates were determined in this paper, and the three methyl groups are located in the equatorial positions with the axial positions occupied by oxygen atoms from two different carboxylate groups.
Abstract: The crystal structures of two triorganotin butyrates were determined. Tricyclohexyltin 2-(p-chlorophenyl)-3-methylbutyrate was determined to have a distorted tetrahedral geometry. Trimethyltin 2-(p-chlorophenyl)-3-methylbutyrate, on the other hand, was found to be polymeric in nature with a trigonal bipyramidal configuration. The three methyl groups are located in the equatorial positions with the axial positions occupied by oxygen atoms from two different carboxylate groups. Copyright © 2003 John Wiley & Sons, Ltd.

TL;DR: In this paper, a Weeks-Chandler-Andersen type perturbation theory is presented for the Helmholtz energy of liquid mixtures consisting of spherical and tetrahedral molecules.
Abstract: A Weeks-Chandler-Andersen type perturbation theory (PT) is presented for the Helmholtz energy of liquid mixtures consisting of spherical and tetrahedral molecules. Use is made of a hard fused sphere anisotropic reference system. The excess properties g E, h E and v E are predicted for the mixtures CS2/CCl4 and Ar, Kr, Xe, CH4/CF4. CCl4 and CF4 are modelled as tetrahedrons, the other substances are treated as spheres. The consequences of molecular shape on the prediction of excess values is discussed. The tetrahedrons are modelled with and without an additional interaction site at the centre of mass. The influence on the excess properties turned out to be small. For the system Xe/CF4 the shape influence on the concentration dependence of the excess properties is small, and is compared with experiment. For the CF4 mixtures it is shown that unlike interaction parameters determined in the liquid phase predict the excess virial coefficients almost within the experimental accuracy.

TL;DR: A new alternating chain compound consisting of gold and silver bridged by cyanides is reported in this article, where the Ag(I) ion is functionalized by 2 triphenyl phosphane ligands, resulting in the formula [Au(C N)2(PPh3)2Ag]n.
