摘　　要：本文报道了K_nZXW_(11)O_(39)·xH_2O和K_nZ’(XW_(11)O_(39))_2·xH_2O(X=B,Si,As;Z=Mg,Ca;Z’=Sr,Ba)两个系列,12种含2A主族元素杂多配合物的合成,并通过元素分析,离子交换实验、电导滴定、IR、UV、XRD和TG-DTA等方法,对配合物进行了表征,比较了它们的热稳定性。Twelve heteropolytungstate compounds containing group 2A elements K_nZXW_(11)O_(39)·xH_2O and K_nZ' (XW_(11)O_(39))_2·XH_2O(X = B, Si, As; Z = Mg, Ca; Z' = Sr, Ba) were synthesi-zed and characterized by elemental analysis, ion exchange, IR UV, XRD and TG-DTA me-thods. Their thermal stability were compared.
