[ 1 ] - On the Polymorphism of 12-Tungstoborate Heteropolyanion: Structure Determination and Its Functionalization with L-proline
A new structure related to previously reported structure of 12-tungstoborate Keggin-type polyoxometalate, K5[BW12O40], was synthesized and its characterization by single crystal X-ray diffraction shows the polymorph structure. Further attempts have been performed to provide three component compounds based on L-proline, lanthanoid cation and K5[BW12O40] (BW12 (II)) under hydrothermal conditions ...
[ 2 ] - Recent Advances in Crystal Engineering from Nanoscience Views: A Brief Review
Crystal engineering has recently emerged as a method of choice for the design and construction of organic as well as metal-organic functional materials. Crystal engineering attempts to establish packing trends in whole families of compounds and seeks to establish connections between structure and function. The utility of crystal engineering has also been expanded to the nanoscience and the deve...
[ 3 ] - Computational study of the intramolecular proton transfer between 6-hydroxypicolinic acid tautomeric forms and intermolecular hydrogen bonding in their dimers
This paper is a density functional theory (DFT) calculation of intramolecular proton transfer (IPT) in 6-hydroxypicolinic acid (6HPA, 6-hydroxypyridine-2-carboxylic acid) tautomeric forms. The transition state for the enol-to-keto transition is reported in the gas phase and in four different solvents. The planar and non-planar dimer forms of 6HPA keto and enol, respectively, were also studied i...
