| Abstract | We investigated the amine-induced structure transformation of four selenidostannates, i.e. [Sn3Se7Fe(TEPA)]n (1), {[Sn2Se6]·4(H+-PR)} (2), {[Sn2Se6]·2[Fe(en)3]} (3), and {[Sn3Se7]n·2n(H+-DBN)} (4) (TEPA = tetraethylenepentamine, PR = piperidine, en = ethylenediamine, DBN = 1,5-diazabicyclo[4.3.0]non-5-ene), which were characterized by single-crystal X-ray diffraction and UV-vis spectroscopy. The TEPA-induced 1D chain structure of [Sn3Se7Fe(TEPA)]n in 1 can undergo cleavage of Se-Fe and Se-Sn bonds to form a 0D dimer unit of [Sn2Se6]2- observed in 2 and 3, induced by PR and en, respectively. More interestingly, under the induction of en and DBN templates, such a 1D chain can counterintuitively fuse into a 2D layered structure of [Sn3Se7]n2n- through the removal of [Fe(TEPA)] species and reformation of Sn-Se bonds. Moreover, these selenidostannates with different structural dimensionalities display photocurrent responses, which make them hold some promise as a potential semiconducting material applied in photoelectric devices. |
