Abstract:
A new 3-D open-framework Li-rich vanadoborate Li10[V12B18O60H6]·28H2O (1) has been successfully synthesized under hydrothermal conditions. The framework of this compound is constructed by the connection of [V12B18O60H6]10- clusters linked through hydrogen bonds and the charge is compensated by disordered Li+ ions. This compound can undergo a phase transition from the crystalline phase to the glassy phase at 220 °C. Interestingly, after transforming into the glass phase, this material exhibits a high Li+ ionic conductivity of 1.77 × 10-2 S cm-1 at 400 °C and the activation energy of lithium ion transport is 0.48 eV.

Most monatomic ions behave as charged spheres, and their attraction for ions of opposite charge is the same in every direction. Consequently, stable structures for ionic compounds result (1) when ions of one charge are surrounded by as many ions as possible of the opposite...

Molecular Solids
Molecular crystalline solids, such as ice, sucrose (table sugar), and iodine, are solids that are composed of neutral molecules as their constituent units. These molecules are held together by weak intermolecular forces such as London dispersion forces, dipole-dipole interactions, or hydrogen bonds, which...

To explain the observed behavior of transition metal complexes (such as colors), a model involving electrostatic interactions between the electrons from the ligands and the electrons in the unhybridized d orbitals of the central metal atom has been developed. This electrostatic model is crystal field theory (CFT). It helps to understand, interpret, and predict the colors, magnetic behavior, and some structures of coordination compounds of transition metals.
CFT focuses on...
