Abstract:
Single crystals of a new reduced vanadate phase, Cs(5)FeV(5)O(13)Cl(6), have been grown from the reaction of metal oxides V(2)O(5) and Fe(2)O(3) in the presence of a metal reducing agent in a eutectic CsCl/NaCl flux. This compound adopts a tetragonal structure (P4/nmm, a = 10.943(3) A, c = 10.535(4) A, Z = 2) that consists of reduced vanadate layers separated by ionic layers comprised of [FeCl(6)](3-) anions and Cs(+) cations. There are two distinct vanadium sites in the structure of this compound; V(4+) is in square pyramidal configuration, and V(5+) has a tetrahedral coordination environment. The (51)V NMR Knight shift and the magnetic susceptibility data indicate the delocalization of the unpaired electron of vanadium. Ferrimagnetic ordering is observed at 5 K.

Ionic Crystal Structures
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...
