Tin monosulfide (SnS) materials, which are a direct band gap semiconductor, have applications in various areas such as photovoltaic solar cells, optoelectronic devices, and polymerization reactions. Especially, SnS having a high absorption coefficient (>104 cm-1) and almost ideal direct band gap of ca. 1.3 eV has recently attracted considerable attention for its ability as a solar absorbent. However, the effectiveness of SnS-based photovoltaic absorber candidates is still low. Therefore, we have focused on the synthesis of new tin sulfide complexes aimed at increasing the thin film deposition efficiency by enhancing the interaction ability between the Sn central metal and the S derivative. A series of novel tin(II) precursors have been successfully synthesized using the β-diketonate and thioketone derivative ligands. These complexes were stabilized by bonding effect with each ligand. It was thought that the tin metal forms strong bonding by monoanionic O,O-chelates with β-diketonates, and S,O-chelates with thioketone ligand. All the synthesized complexes were fully characterized by NMR and FT-IR spectroscopy along with elemental analysis and thermogravimetric (TG) analysis. Newly synthesized Sn complexes have potential properties for single source precursors to prepare metal sulfide materials.
