Abstract:
Three heterometallic [LnIII 2CoII 5] clusters with the formulas [LnIII 2CoII 5(L1)2(L2)2(L3)2(OAc)4(NO3)2]·4CH3CN (LnIII = Gd (1), Tb (2), and Dy (3); HL1 = (E)-1-((2-hydroxy-3-methoxybenzylidene)amino)naphthalen-2-ol, HL2 = 1-aminonaphthalen-2-ol, and HL3 = trimethylopropane) have been obtained via self-assembly of mixed ligands strategy. Significantly, cluster 1 displays a larger magnetocaloric effect (MCE) (-ΔSm = 36.83 J kg-1 K-1 at 2.0 K and 7.0 T), while cluster 3 shows slow magnetic relaxation behavior under zero dc field. Moreover, clusters 1-3 as heterogeneous catalysts can effectively convert CO2 with epoxides and benzylamine to form oxazolidinones under mild conditions. To our knowledge, it is the first reported bifunctional heterometallic heptanuclear clusters which show well magnetic behaviors and can effectively catalyze CO2 with epoxides and amines under mild conditions simultaneously.

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...

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...
02:58Crystal 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...
