Why does carbon disulphide (CS2) exist but not carbon sulphide (CS)?

Question

cant CS be formed with carbon donating one lone pair of electrons forming dative bonding?

Answer 1

Coz the triple bond of CS is too reactive!!!

Answer 2

The CS triple bond is just too reactive.  The orbital overlap between carbon and sulfur is not as good as it is for oxygen (CO is stable).

Answer 3

it has aCAS #

these people believe it exists:

and these:

and these have a process for generating carbon monosulfide (CS) in quantity :

& the list goes on & on,

================================

the bonding is just as in CO with its +C triple bond O-

.... +C triple bond S-
