Solvothermal synthesis, crystal structure and luminescence of the first organic amine templated europium sulfate

Reaction in situ found in the synthesis of a series of lanthanide sulfate complexes and investigation on their structure, spectra and catalytic activity

“…The detail hydrogen bondings of the complexes are listed in Tables S7-S12. All these are comparable with those found in other reported lanthanide sulfate complexes[55,[60][61][62].…”

Solvothermal synthesis, crystal structure and luminescence property of a new 1D organic amine templated europium sulfate with helical chains

“…The red emission of the 5 D 0 → 7 F 2 transition at 616 nm is the most intense [32]. Above luminescent property is in agreement with the reported Eu compounds [12,13]. Interestingly, the luminescence intensity of 2D [C 2 N 2 H 10 ] 1.5 [Eu(SO 4 ) 3 (H 2 O)]·2H 2 O is much stronger than 3D (C 2 H 8 N) 9 [Eu 5 (SO 4 ) 12 ]·2H 2 O, while the luminescence intensity of 1D compound 1 is stronger than 2D Eu sulfate (We measured solid state emission spectra under same conditions).…”

“…Recently, new sulfates have been elaborated using organic templates [7]. Since the first organically templated cadmium sulfate synthesized by Rao, there has been a growing interest in the study of organic amine templated sulfates framework architectures [7][8][9][10][11][12][13][14][15][16][17][18][19][20][21][22][23][24]. Indeed, the ability of rare earth elements to adopt a large range of coordination numbers and flexible Ln-O bond lengths [25] [23] is an interesting 1D ladder-like structure.…”

Second structural directing agent induces the formation of 1D organic templated terbium sulfate

“…[4][5][6][7] Compared with 3d transition metals such as Fe, Mn, V and Zn, the rare-earth elements can adopt a large range of coordination numbers from 8 (LnO 8 ) to 12 (LnO 12 ) and flexible Ln-O bond lengths allow the formation of new inorganic lanthanide sulfate topological frameworks. [7][8][9][10][11][12][13][14][15][16][17][18][19][20][21][22] Up to now, successful examples including organic amine templated lanthanide sulfates materials have been reported. For example, [(C 4 H 16 N 3 )La(SO 4 ) 3 ]$H 2 O 7,20,6a is a 1D lanthanum sulfate containing infinite zigzag {-La-m-O-Lam-O-La-} chains and the inorganic framework of [C 6 N 4 H 22 ] 1.5 [Ho 2 (SO 4 ) 6 H 2 O] 21 is an interesting 1D triple ladder; [C 2 N 2 H 10 ] 1.5 [Eu(SO 4 ) 3 (H 2 O)]$2H 2 O 23 is a 2D europium sulfate which contains interesting corrugated layers in the inorganic framework; (C 2 H 8 N) 9 [Eu 5 (SO 4 ) 12 ]$2H 2 O 24 is the first 3D rare earth sulfate which contains two kinds of intersecting extra large 20-membered ring channels.…”
