Two　new　inorganic　frameworks　HLa(H2O)5[La(H2O)6]2[La(H2O)2(GeW11039)]2　center　dot　7H(2)0　(1)　and　HK(H2O)La-3(H2O)(15)[La(H2O)3(GeW11O39)](2)center　dot　38H(2)O　(2)　based　on　1:1　type　lanthanide-substituted　polyoxometalates　(LSPs)　have　been　synthesized　under　hydrothermal　reactions.　Compounds　1　and　2　are　characterized　by　single-crystal　X-ray　diffraction　analysis,　thermogravimetry　analysis,　infrared　spectroscopy　and　X-ray　powder　diffraction　analysis.　Interestingly,　Compounds　1　and　2　can　be　selectively　obtained　by　simply　controlling　the　reaction　temperatures　under　similar　conditions.　Both　1　and　2　are　three-dimensional　structures　built　from　lanthanide-substituted　polyoxoanions　[La(H2O)(n)(GeW11O39)](5-)　building　blocks.　Furthermore,　the　ion-conducting　properties　of　1　and　2　were　investigated.　(C)　2017　Elsevier　B.V.　All　rights　reserved.
