摘　　要：The novel class of inorganic nanoclusters, \{\[AlO\-4Al\-\{12\}(OH)\-\{24\}(H\-2O)\-\{12\}\]\}\{\[SiW\-\{11\}O\-\{39\}CoCl\]\}\511H\-2O, \{\[AlO\-4Al\-\{12\}(OH)\-\{24\}(H\-2O)\-\{12\}\]\}\{\[P\-2W\-\{18\}O\-\{62\}\]\}Cl\533H\-2O and \{\[AlO\-4Al\-\{12\}(OH)\-\{24\}(H\-2O)\-\{12\}\]\}\-2\[NaP\-5W\-\{30\}O\-\{110\}\]\524H\-2O, consisting of Keggin cations and heteropolyoxometalates, has been synthesized and characterized by ICP, IR and NMR. It is proved that the intrinsic identities of Keggin cation and heteropolyanions of the clusters are preserved within the gels.The novel class of inorganic nanoclusters, \{\[AlO\-4Al\-\{12\}(OH)\-\{24\}(H\-2O)\-\{12\}\]\}\{\[SiW\-\{11\}O\-\{39\}CoCl\]\}\511H\-2O, \{\[AlO\-4Al\-\{12\}(OH)\-\{24\}(H\-2O)\-\{12\}\]\}\{\[P\-2W\-\{18\}O\-\{62\}\]\}Cl\533H\-2O and \{\[AlO\-4Al\-\{12\}(OH)\-\{24\}(H\-2O)\-\{12\}\]\}\-2\[NaP\-5W\-\{30\}O\-\{110\}\]\524H\-2O, consisting of Keggin cations and heteropolyoxometalates, has been synthesized and characterized by ICP, IR and NMR.
