It is a resonance structure, meaning there are two possible ways to write the structure.
:S=C=S:: or ::S=C=S:
(note - "::" refers to two electron pairs)
These structures are the best because they give the lowest formal charge, and the structure with the formal charge closest to zero is the best choice.
Formal charge can be calculated in the following manner:
# of valence electrons - # of bonds shared - number of unbonded electrons
So, for the structure on the left, the formal charge is:
S(left) = 6 - 2 - 2 = +2
C = 4 - 4 - 0 = 0
S(right) - 6 - 2 - 4 = 0
This structure, and the other one shown both give the lowest formal charge and are therefore the best choices.
