Embedding metal clusters in surface-supported metal-organic frameworks gives rise to multinuclear metal-organic coordination structures (MMOCs). The controllable configurations, exposed clusters, and multilevel interactions of MMOCs imply numerous potential applications, such as in catalysis, light-energy conversion, spintronics, and molecular electronics. Thus, the fabrication of MMOCs has been investigated extensively. According to the formation mechanism of metal clusters, we summarize five types of MMOCs. Attractive properties, e.g., magnetism, charge transfer and chirality, emerge in these systems. The surface-supported feature enables researchers to detect these properties via surface-sensitive techniques, such as scanning tunneling microscopy/spectroscopy, X-ray photoelectron spectroscopy, noncontact atomic force microscopy and local contact potential difference measurement. In addition, the results obtained from density functional theory calculations can be mutually verified with experiments. These studies pave the way for further applications of MMOCs.

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.

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...
