Abstract: | Two rare earth metal‐organic framework compounds Ybsip(H2O)5] · 3H2O ( 1 ) and Dysip(H2O)4] ( 2 ) (NaH2sip: 5‐sulfoisophthalic acid sodium salt) were synthesized hydrothermally, and characterized by single‐crystal X‐ray diffraction, elemental analysis, and FT‐IR spectroscopy. In complex 1 , each YbIII atom is nine‐coordinate with a distorted monocapped tetragonal prismatic arrangement. Two carboxylate groups of each sip3– molecule adopt the same μ1‐η1:η1 chelating coordination model connecting two YbIII atoms. The oxygen atoms of the sulfonate group do not participate in coordination with YbIII. The whole sip3– molecule acts as a μ2 bridge to form an one‐dimensional (1D) chain structure. The 1D chains are linked by hydrogen bonding to generate two‐dimensional layers, and are further combined together to form a three‐dimensional structure. In complex 2 , the DyIII atom is nine‐coordinate with a distorted monocapped tetragonal antiprismatic arrangement. In each sip3– anion, two carboxylate groups take the same μ1‐η1:η1 chelating coordination mode, only an oxygen atom of sulfonate group bond to DyIII ion. The whole ligand sip3– acts as a μ3 bridge linking three different DyIII ions to generate a wave‐like two‐dimensional network with (6,3) topological structure. The two‐dimensional networks are further linked by O–H ··· O hydrogen bonds to form a three‐dimensional structure. The thermal and luminescent properties of both complexes are investigated. |
