orthogonal and nested model

I'm working with a orthogonal and nested model (mixed).
I have  four factors, A,B,C,D;
A and B are fixed and orthogonal
C is nested in AB interaction
and finally, D is nested in C.
 I would like to model the following
Y_ijklm=Mu+A_i+B_j+AB_ij+C_k(ij)+D_l(k(ij))+Error_m(...)

I used the next command

summary(aov(abund~A*B + C % in % A:B + D % in % C % in % A:B ,datos))

Is it the correct formula syntax?

Thaks for all.

Marcelo.
