Abstract:
New tetranuclear supramolecular precursors [(R-C[triple bond, length as m-dash]C-C[triple bond, length as m-dash]C)Ag(PPh3)]4 (R = iPr and chx) are employed to construct three polynuclear silver(i) alkyl-1,3-diynyl cluster complexes (1-3) that bear the same novel trigonal bipyramidal Ag5 core consolidated by silver-ethynide and argentophilic interactions. The present results strongly suggest that the assembly of high-symmetry medium-nuclearity clusters 1-3 is initiated by the accretion of additional Ag(i) ions by the Ag4 template of the precursors through argentophilic (<3.4 Å) interaction, and demonstrate that core transformation is an effective synthetic route to high-symmetry metal clusters.

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.

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,...
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...
