Abstract:
Dizinc selenium dichloride trioxide, beta-Zn(2)(SeO(3))Cl(2), a monoclinic polymorph of the orthorhombic mineral sophiite, has a structure built of distorted ZnO(4)Cl(2) octahedra, ZnO(2)Cl(2) tetrahedra and SeO(3)E tetrahedra (E being the 4s(2) lone pair of the Se(IV) ion), joined through shared edges and corners to form charge-neutral layers. The Cl atoms and the Se lone pairs protrude from each layer towards adjacent layers. The main structural difference between the mineral and synthetic polymorphs lies in the packing of the layers.

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...

Crystal Field Theory - Octahedral Complexes
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...
