摘　　要：Three new Dawson-type HPCs:K14·24H2O,K15H3·26H2O and K15H3·27H2O were synthesized for the first time.They are tungstophosphoric and molybdotungstophosphoric HPCs substituted by Ni or Cu.The intermediate product K10Na2H2P2W16O60 was synthesized from Na2WO4·2H2O and Na4HPO4·12H2O.The structures of the compounds were confirmed by IR,UV,XAFS and elemental analysis.Three new Dawson-type HPCs:K_(14)·24H_(2)O,K_(15)H_3·26H_2O and K_(15)H_3·27H_2O were synthesized for the first time.They are tungstophosphoric and molybdotungstophosphoric HPCs substituted by Ni or Cu.The intermediate product K_(10)Na_2H_2P_2W_(16)O_(60) was synthesized from Na_2WO_4·2H_2O and Na_4HPO_4·12H_2O.The structures of the compounds were confirmed by IR,UV,XAFS and elemental analysis.
