Abstract:
The title compound, [Dy2(C8H7O2)6(C12H8N2)2], forms binuclear complexes, viz. di-mu-4-methylbenzoato-kappa4O:O'-bis[bis(4-methylbenzoato-kappa2O,O')(1,10-phenanthroline-kappa2N,N')dysprosium(III)] tetra-mu-4-methylbenzoato-kappa8O:O'-bis[(4-methylbenzoato-kappa2O,O')(1,10-phenanthroline-kappa2N,N')dysprosium(III)]. There are two independent binuclear complexes in the asymmetric unit, both of which are centrosymmetric. In one, the Dy(III) ions are linked by two bridging 4-methylbenzoate groups, while in the other, the Dy(III) ions are linked by four bridging 4-methylbenzoate groups. The remaining 4-methylbenzoate groups and 1,10-phenanthroline units coordinate to just one metal ion in bidentate modes.

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.
02:52Stereoisomerism
Isomers are different chemical species that have the same chemical formula.
Transition metal complexes often exist as geometric isomers, in which the same atoms are connected through the same types of bonds but with differences in their orientation in space. Coordination complexes with two different ligands in the cis and trans positions from a ligand of interest form isomers. For example, the octahedral [Co(NH3)4Cl2]+ ion has two isomers (Figure 1) In the cis...

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...
02:46Crystal Field Theory - Tetrahedral and Square Planar Complexes
Crystal field theory (CFT) is applicable to molecules in geometries other than octahedral. In octahedral complexes, the lobes of the dx2−y2 and dz2 orbitals point directly at the ligands. For tetrahedral complexes, the d orbitals remain in place, but with only four ligands located between the axes. None of the orbitals points directly at the tetrahedral ligands. However, the dx2−y2 and dz2 orbitals (along the Cartesian axes) overlap with the ligands less than the dxy,...
