Abstract:
A new polymorph of copper(ii) vanadate, Cu2(VO4)(OH), containing a layered magnetic sublattice, is synthesized by a hydrothermal reaction. It displays a 3D framework based on copper(ii) oxide layers which are further connected by VO4 tetrahedra through corner-sharing {V-O-Cu} bonds in the system. The copper(ii) oxide layer is constructed by the interactions of Cu3(μ3-OH) building units. Magnetic properties are investigated by means of magnetic susceptibility, magnetization and heat capacity measurements. The results indicate a typical long-range canted antiferromagnetic ordering below ∼10 K and weak spin frustration arising from the competition between antiferromagnetic and ferromagnetic interactions inside the irregular Cu3(μ3-OH) triangles.

Colors and Magnetism
When atoms or molecules absorb light at the proper frequency, their electrons are excited to higher-energy orbitals. For many main group atoms and molecules, the absorbed photons are in the ultraviolet range of the electromagnetic spectrum, which cannot be detected by the human eye. For coordination compounds, the energy difference between the d orbitals often allows photons in the visible range to be absorbed and emitted, which is seen as colors by the human...

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...
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...
