چکیده

By the reaction of TBA(4)H(4)[γ-SiW(10)O(36)] (TBA = tetra-n-butylammonium) with AgOAc (OAc = acetate) using dimethylphenylsilane as a reductant in acetone, a unique polyoxometalate containing a discrete octahedrally shaped [Ag(6)](4+) cluster, TBA(8)[Ag(6)(γ-H(2)SiW(10)O(36))(2)]·5H(2)O, could be synthesized, and the molecular structure was determined.

Optical properties of the hydrated charged silver tetramer and silver hexamer encapsulated inside the sodalite cavity of an LTA-type zeolite.

The optical spectra in the UV-VIS region of the hydrated doubly charged tetramer Ag4(2+) and hydrated multiply charged hexamer Ag6(p+) silver clusters encapsulated inside the sodalite cavity of an LTA-type zeolite have been systematically predicted using DFT, TD-DFT and CASSCF/CASPT2 methods. The optical behaviour of the model hydrated clusters [Ag6(H2O)8(Si24H24O36)](p+) is very sensitive to t...

Octa­rubidium di-μ-sulfato-κ4 O:O′-bis­[cis-dioxido-cis-disulfatotungstate(VI)]

The title compound, Rb(8)[W(2)O(4)(SO(4))(6)], was precipitated from a melt of tungsten(VI) oxide and rubidium sulfate in rubidium disulfate. The unit cell contains two discrete [{W(VI)O(2)(SO(4))(2)}(2)(μ-SO(4))(2)](8-) units connected by Rb-O coord-ination. The W atom is octahedrally surrounded by two oxide ligands, two terminal sulfate ligands and two bridging sulfate groups. One Rb atom is ...

Simultaneous self-assembly of a cage-like silver(I) complex encapsulating an Ag6 neutral cluster core and carbon dioxide fixation.

A novel mixed-valent Ag(I)/Ag(0) T(h)-Ag(34) cage was obtained by a one-pot ultrasonic reaction. In the shell of the cage, CO(3)(2-) anion is derived from atmospheric CO(2) and adopts a rare μ(6) bridging mode to link the Ag(I) ions. In the core of the cage, an unprecedented neutral metal cluster with six zero-valent silver atoms is encapsulated.

Poly[(μ2-4,4′-bipyridine)bis­(μ4-5-tert-butyl­isophthalato)bis­(μ3-5-tert-butyl­isophthalato)di-μ3-hydroxido-penta­zinc(II)]

The asymmetric unit of the title compound, [Zn(5)(C(12)H(12)O(4))(4)(OH)(2)(C(10)H(8)N(2))](n), consists of three Zn(II) ions (one of which is located on a twofold rotation axis), two 5-tert-butyl-isophthalate ligands, one 4,4'-bipyridine ligand and one hydroxide group. The five Zn(II) ions form a penta-nuclear zinc cluster, which is further bridged by ten organic ligands, forming two-dimension...
