Ternary metal sulfides having layered morphology are considered as potential active materials for various applications. Herein, Nb 3 VS 6 is synthesized topochemically for the first time using a Nb-V-HDA complex having a lamellar structure by employing H 2 S gas as the sulfidation agent. Nb 3 VS 6 , as an anode for SIBs, exhibited a specific capacity of 101.15 mA h g -1 at 0.5 A g -1 , along with excellent cycling stability with 100% capacity retention after 2500 cycles.
