In the present work, which aims at searching for bound sates, the interactions of the D-multi-ρ systems are investigated by means of the formalism of the fixed-center-approximation to Faddeev equations. Reproducing the states of f2 (1270) and D1 (2420) dynamically in the two-body ρρ and ρD interactions, respectively, as the clusters of the fixed center approximation, the state of D(3000)0 is found as a molecule of D-f2 or ρ-D1 structures in the three-body interactions, where we determine its quantum number JP = 2- and find another possible state of D2 (3100) with isospin I=3/2. In our results, there are some other predictions with uncertainties, a D3 (3160) state with I(JP) = (1)/(2) (3+) in the four-body interactions, a narrow D4 (3730) state with I(JP) = (1)/(2) (4-), a wide D4 (3410) state of I(JP) = (1)/(2) (4-), and another wide D4 (3770) state but with I(JP) = (3)/(2) (4-) in the five-body interactions, and a D5 (3570) state with I(JP) = (1)/(2) (5+) in the six-body interactions. Our results are consistent with the findings of quark models.
