As I understand it is a weak hydrogen bond interaction, but not impossible.
Maybe this reference will help you:
L. Shimoni and J. P. Glusker
"Hydrogen bonding motifs of protein side chains: Descriptions of binding
of arginine and amide groups"
Protein Structure (1995), 4, 65-74
There are a few web pages were you can find N-H -- N hydrogen bond
definitions. For example: http://www.lsbu.ac.uk/water/hbond.html
I hope that helps,

Dear Karen,
this hydrogen bond is rather impossible, unless you work at a very
basic pH or in a very specific environment. Are you sure that there is
no other interpretation of your electron density?
Greetings

Dear All,
I was wondering if you know of some references with regard to
hydrogen bond interactions between a guanidium group of an Arg
residue with another amine group in any structure? Thanks for your
help.
Karen
