AI Article Synopsis
- This study introduces new 2-D In-Sn-Q chalcogenido-metalate compounds, which have been less commonly explored compared to ternary In-Sb-Q structures.
- The compounds are synthesized using metal-phenanthroline templates and form isostructural 2-D porous networks with unique large-ring structures.
- The materials demonstrate photocurrent responses, revealing that selenides have stronger photocurrents than sulfides, and the current intensity is influenced by the metal-phenanthroline cations used.
Article Abstract
A lot of ternary In-Sb-Q (Q = S, Se) chalcogenido-metalates with amines or complex cations have been recently reported for their diverse structures, however, such a type of In-Sn-Q chalcogenido-metalate has been rarely announced. Herein, we report a series of 2-D In-Sn-Q compounds prepared using a metal-phenanthroline cationic template, [M(Phen)3](In2Sn2Q8)·(amine)·nH2O (M = Ni(II), Fe(II) or Co(II); amine = cyclohexylamine (Cha) or 1,6-diaminohexane (Dah); Q = S or Se). Their anions are isostructural and a 2-D porous network with large 16-tetrahedron-rings. The 2-D network joint of In-Sn-Q is a (In/Sn)3Q3 six-membered ring, which is different from the Sn3Q4 pseudosemicube of most 2-D Sn-Q binary compounds. The materials exhibit photocurrent response properties measured using a photo-electrochemical cell. The result shows that (1) the selenides exhibit more intense photocurrents than the sulfides and (2) the current intensity is related to the metal-phenanthroline cations.
