Cation-induced assembly of the first mixed molybdenum–vanadium hexadecametal host shell cluster anions

Abstract

Two novel hexadecametal–oxygen cluster compounds, {Ni[(NH2)2(C2H4)2NH]2}3[PMoVI5MoV3VIV8O44]·[(NH2)2(C2H4)2NH]·H2O 1 and {Co[(NH2)2(C2H4)2NH]2}2Na[PMoVI6MoV2VIV8O44]·8H2O 2 are synthesized by a hydrothermal method, and characterized by X-ray crystallography, showing that the anion of 1 has a novel tetra-capping mode, and that the first hexadecametal–oxygen host shell is observed in 2.
