You are not correctly coding single-staff polyphony — I suggest you  
(re?)read the appropriate documentation sections, starting with
<http://lilypond.org/doc/v2.13/Documentation/user/lilypond-learning/ 
Combining-notes-into-chords#Combining-notes-into-chords>

Hint: << ... >> is not used for chords.

Hope this helps!
