Diagonal matrix from multiple columns of an array

I have the array

M=[a b c;
   d e f;
   g h i]

and I want to construct an array composed of several diagonal arrays in the form:

N=[0 a d 0 0;
   0 0 b e 0;
   0 0 0 c f;
   g 0 0 0 0;
   0 h 0 0 0]

or basically place the individual columns of M into pre-assigned positions (1 2 -3) in N. How can I do this without a loop?
