A　series　of　lanthanide　sulfates　and　lanthanide　sulfonate-carboxylates,　[Ln(2)(phen)(2)(SO4)(3)(H2O)(2)](n)　(I:　Ln=Nd　(1a),　Sm(1b),　Eu(1c),　phen=1,10-phenanthroline)　and　[Ln(phen)(2-SBA)(BZA)](n)　(II:　Ln=Sm(2a),　Eu(2b),　Dy　(2c),　2-SBA=2-sulfobenzoate,　BZA=benzoate)　have　been　hydrothermally　synthesized　from　lanthanide　oxide,　2-mercaptonbenzoic　acid　with　phen　as　auxiliary　ligand　and　characterized　by　single-crystal　X-ray　diffraction,　elemental　analyses,　IR　spectra,　TG　analyses　and　luminescence　spectroscopy.　Interestingly,　SO42-　anions　in　I　came　from　the　in　situ　deep　oxidation　of　thiol　groups　of　2-mercaptonbenzoic　acid　while　2-sulfobenzoate　and　benzoate　ligands　in　II　from　the　middle　oxidation　and　desulfuration　reactions　of　2-mercaptonbenzoic　acid.　Compounds　I　are　organic-inorganic　hybrid　lanthanide　sulfates,　which　have　rare　one-dimensional　column-like　structures.　Complexes　II　are　binuclear　lanthanide　sulfonate-carboxylates　with　2-sulfobenzoate　and　benzoate　as　bridges　and　1,10-phenanthroline　as　terminal.　Photoluminescence　studies　reveal　that　complexes　I　and　II　exhibit　strong　lanthanide　characteristic　emission　bands　in　the　solid　state　at　room　temperature.　(C)　2014　Elsevier　Inc.　All　rights　reserved.
