Polyoxometalate (POM)-encapsulated Ag nanoclusters have attracted increasing research interest due to their intriguing structural diversities and synergistic catalytic properties; however, the types of POM ligands are limited to the multidentate lacunary or ring-shaped POMs. Herein, we develop an asymmetric POM-induced synthetic strategy to synthesize a superatomic {Ag8}6+ cluster encapsulated by six redox-active mixed-addendum P2W15Nb3 ligands, (C16H36N)6Na4H24[Na2Ag8(P2W15Nb3O61)6]·36CH3CN ({Ag8@(P2W15Nb3)6}). The oriented aggregation of Ag+ ions is attributed to the unevenly distributed electron density over the asymmetric mixed-addendum P2W15Nb3 ligands. The resulting {Ag8@(P2W15Nb3)6} cluster exhibits interesting photothermal and photocatalytic performance due to the redox activity of P2W15Nb3 ligands. This work presents a new research avenue for the construction of Ag nanoclusters induced by asymmetric all-inorganic POM ligands and will stimulate the structural exploration and catalytic applications of atomically precise metal nanoclusters.

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...

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,...
