Answer:
Carbon trisulfide or tetracarbon trisulfide.
Step-by-step explanation:
I don't know if this compound actually exists. The C is carbon and the S is sulfur. The carbon retains its name and is in first position in the name. A compound of sulfur is given the nickname "sulfide." The number of S atoms needs to be identified using the latin prefix "tri." The number of C atoms is often not identified in chemical naming, based on the irritating assumption that anyone looking at the three sulfurs would be able to determine that 3 carbons are necessary. But that is often not obvious, as in this case. So I prefer adding the latin prefix for 4 (tetra-) for the sulfur, to make it tetrasulfur trisulfice. {Try fitting that into a bottle}.
