The　utilization　of　a　rationally　designed　T-shaped　ligand　4,4＇,4　＇＇-(1H-benzo[d]imidazole-2,4,7-triyl)tribenzoic　acid　(H(3)BTBA)　as　the　platform　for　constructing　metal-organic　frameworks　(MOFs)　with　structure　diversity　was　achieved.　Five　new　MOFs,　[Zn4O(BTBA)(2)]　(BUT-34),　[Fe2CoO(BTBA)(2)(H2O)(3)]　(BUT-35),　[Cu-9(BTBA)(4)(H2O)-(DMA)]　(BUT-36),　[Eu-2(HBTBA)(2)(OH)(2)(H2O)(6)]　(BUT-37),　and　[In(BTBA)(DMF)]　(BUT-38)　(BUT　=　Beijing　University　of　Technology),　have　been　solvothermally　synthesized　and　structurally　characterized.　Combining　with　several　popularly　used　metal-cluster　secondary　building　units,　the　five　MOFs　show　novel　structural　features.　BUT-34　with　typical　tetranuclear　Zn4O　clusters　shows　three-dimensional　(3D)　networks　with　a　new　(3,6)-connected　topology.　BUT-35　exhibits　a　(3,6)-connected　flu-3　network　with　trinuclear　[Fe2Co(mu(3)-O)]　clusters.　BUT-36　represents　a　mixed　Cu(II)/Cu(I)　based　3D　framework,　in　which　the　T-shaped　ligand　adopts　different　coordination　modes.　However,　BUT-37　and　-38　consist　of　binuclear　Eu-2　paddle-wheel　clusters　and　single　In(III)　ions　with　two-dimensional　layer　structures,　respectively.　Clearly,　the　structural　diversity　of　these　MOFs　can　be　attributed　to　the　unique　structure　and　variable　coordination　patterns　of　the　T-shaped　ligand.　This　work　thus　enriches　the　in　the　structural　design　based　on　the　low-symmetric　ligands,　and　thereby　function　exploration.
