Abstract:
Three defect-dicubane coordination clusters related to our previously reported butterfly compound, [Co2Dy2(L)4(NO3)2(THF)2]·4THF (1) and formulated as [Co2Dy2(L)4(NO3)2(MeOH)2]·2CH2Cl2 (2), [Co2Dy2(L)4(NO3)2(DMF)2]·2C2H6CO (3) and [Zn2Dy2(L)4(NO3)2(MeOH)2]·2CH2Cl2 (4) were synthesised and characterised. All show typical SMM behaviour which is steered through the nature of the solvent molecule coordinated to the central 3d ions. The ZnDy, (4) provides experimental proof of the suggestion that in such CoDy compounds two major relaxation pathways can be important in determining the overall magnetic behaviour of CoII-4f systems.

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...
02:51Metal-Ligand Bonds
In these complexes, transition metals form coordinate covalent bonds, a kind of Lewis acid-base interaction in which both of the electrons in the bond are contributed by a donor (Lewis base) to an electron acceptor (Lewis acid). The Lewis acid in...
02:34Structural Isomerism
Isomers are different chemical species that have the same chemical formula. Structural isomerism of coordination compounds can be divided into two subcategories, the linkage isomers and coordination-sphere isomers.
Linkage isomers occur when the coordination compound contains a ligand that can bind to the transition metal center through two different atoms. For example, the CN− ligand can bind through the carbon atom or through the nitrogen atom. Similarly, SCN− can be...

02:58Crystal 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...
03:02Colors 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 eye.
