文摘

A series of new lanthanide thiostannates(IV), [Y₂(dien)₄(渭-OH)₂]Sn₂S₆ (1, dien = diethyl-enetriamine), (tetaH)₂[Ln₂(teta)₂(tren)₂(渭-Sn₂S₆)]Sn₂S₆ [Ln = Eu (2), Sm (3); teta = triethylenetetramine; tren = tris(2-aminoethyl)amine] and [Eu₂(tepa)₂(渭-OH)₂(渭-Sn₂S₆)](tepa)_0.5路H₂O (4, tepa = tetraethylene-pentamine) were solvothermally synthesized and structurally characterized. 1 consists of a binuclear [Y₂(dien)₄(渭₂-OH)₂]⁴⁺ cation and a discrete dimeric [Sn₂S₆]^{4鈥?/sup> anion. Both 2 and 3 are isostructural and composed of [Ln₂(teta)₂(tren)₂(渭-Sn₂S₆)]2+ cations, protonated triethylenetetramines (tetaH), and discrete dimeric [Sn₂S₆]4鈥?/sup> anions. A Sn₂S₆4鈥?/sup> anion bridges two [Ln(teta)(tren)]3+ cations via the trans-S_t (t = terminal) atoms to form the first examples of inorganic鈥搊rganic hybrid thiostannate cations [Ln₂(teta)₂(tren)₂(渭-Sn₂S₆)]2+. 4 consists of one-dimensional (1-D) neutral chains [Eu₂(tepa)₂(渭-OH)₂(渭-Sn₂S₆)]_n built up from the linkage of dinuclear complex cations [Eu₂(tepa)₂(渭₂-OH)₂]4+ and bridging anions [Sn₂S₆]4鈥?/sup>, free tepa molecules, and lattice water molecules. The present compounds exhibit wide-band gap semiconducting properties with absorption band edges between 2.40 and 2.91 eV.}
