Two　new　layered　and　porous-layered　borates　([H2dap][B7O11(OH)]　(1,　dap　=　1,2-propanediamine)　and　[H3O]K3.52Na3.48{Al2[B7O13(OH)][B5O10][B3O5]}[CO3]　(2))　have　been　solvothermally　made.　1　features　a　2D　layer　made　of　the　[B7O13(OH)]6-　cluster,　in　which　H2dap　is　located　in　the　windows　of　the　layers.　The　fundamental　building　block　(FBB)　[B7O13(OH)]6-　cluster　in　1　represents　a　new　type　of　FBB　of　the　hepta-borate　family.　2　is　a　novel　aluminoborate　with　a　3D　porous-layered　structure　formed　by　three　types　of　oxoboron　clusters,　[B7O13(OH)]6-,　[B5O10]5-　and　[B3O7]5-,　respectively.　The　strict　alternation　of　the　different　oxoboron　clusters　and　AlO4　tetrahedra　leads　to　the　abundant　channel　systems　of　the　structure.　2　is　the　first　aluminoborate　(ABO)　containing　three　types　of　oxoboron　clusters　and　the　first　3D　porous-layered　ABO　with　seven　types　of　channels.　UV-vis　diffuse　reflectance　spectra　reveal　that　both　of　them　are　wide　band-gap　semiconductors　and　have　potential　applications　in　UV　regions.　©　2020　The　Royal　Society　of　Chemistry.
