资源简介：
Two novel hybrid polyoxovanadates that are functionalized
by (4-aminophenyl)arsonic
acid ligands form upon the reduction of vanadates(V) in aqueous systems,
whereby the underlying condensation reactions are influenced by the
nature of the employed acid. In the presence of Cl– ions that derive from hydrochloric acid, a tetradecanuclear
cage structure [VIV14O16(OH)8-(O3AsC6H4-4-NH2)10]4–, whose cavity
contains stabilizing halide ions and water molecules,
is obtained. When nitric acid is used, a decanuclear [V10O18(O3AsC6H4-4-NH2)7(DMF)2]5– cluster
can be isolated. The latter organizes into a hexagonal packing arrangement
in the solid state.
