In the present work, which aims at searching for bound states, the interactions of the D -multi- systems are investigated by means of the formalism of the fixed-center approximation to Faddeev equations. Reproducing the states of 
and 
dynamically in the two-body 
and 
interactions, respectively, as the clusters of the fixed-center approximation, the state of 
is found as a molecule of 
or 
structures in the three-body interactions, where we determine its quantum number 
and find another possible state of 
with isospin I = 3/2 . In our results, there are some other predictions with uncertainties, a 
state with 
in the four-body interactions, a narrow 
state with 
, a wide 
state of , and another wide 
state but with 
in the five-body interactions, and a 
state with 
in the six-body interactions.
