Mixed Molybdenum-Vanadium Polyoxoanion-Bridged Trimetallic Nanocluster Complexes: Hydrothermal Syntheses and Crystal Structures of {Mo_6~(VI)Mo_2~VV_8~(IV)O_(40)-(PO_4)[Co(phen)_2(H_2O_]_2}[Co_2(phen)_2(OH)_2(H_2O)_4]_(1/2) and {Mo_5~(VI)Mo_3~VV_8~(I

摘要

Two novel trimetallic nanocluster complexes, {Mo_6~(VI)Mo_2~VV_8~(IV)O_(40)-(PO_4)[Co(phen)_2(H_2O_]_2}[Co_2(phen)_2(OH)_2(H_2O)_4]_(1/2) (1) (phen=1,10'-phenanthroline) and {Mo_5~(VI)Mo_3~VV_8~(IV)O_(40)(PO_4)[Co(phen)(en)(H_2O)]_2}[Co(phen)_3]·1.5H_2O (2) (phen=1,10'-phenanthroline, en=ethylenediamine), which are the first examples of mixed molybdenum-vanadium polyoxoanion bridged cluster complexes, have been hydrothermally prepared and characterized by X-ray crystallography.
