摘要

A novel polyoxometalate [Co_4(HPO_3)_2(C_(12)H_8N_2)_8(H_2O)_2](H_3O)[PW_9~(VI)V_3~(IV)O_(40)(V~(IV)O)_2] centre dot H_2O (1) has been synthesized under hydro-thermal conditions.The X-ray crystallography shows that 1 contains a novel bi-capping pseudo-Keggin type heteropolyanion [PW_9~(VI)V_3~(IV)O_(40)O_(40)(V~(IV)O)_2]~(5-) and a four-nuclei cation [Co_4(HPO_3)_2(C_(12)H_8N_2)_8(H_2O)_2]~(4+).The different heteropolyanions are linked by water molecules and the cations [Co_4(HPO_3)_2(C_(12)H_8N_2)_8(H_2O)_2]~(4+) through the hydrogen bonds,to form an extensive three-dimensional supra-molecular assembly.
