Thermal decomposition of four single‐source precursors of the type (Et2Sb)2E and Et3SbE (E = S, Se) at 170 °C in the presence of suitable capping agents yielded binary Sb2S3 and Sb2Se3 nanowires. In addition, simultaneous decomposition of (Et2Sb)2S and(Et2Sb)2Se gave the ternary phase Sb2(S,Se)3 with almost equal S and Se concentrations. The materials were characterized by XRD, REM, EDX, ED and HRTEM. Binary Sb2S3 and Sb2Se3 nanowires as well as ternary Sb2(S,Se)3 nanowires were synthesized by thermal decomposition of four novel single‐source precursors of the type (Et2Sb)2E and Et3SbE (E = S, Se) in the presence of suitable capping agents and characterized by XRD, REM, EDX, ED and HRTEM.
