You can always use a Scheme string escape:

  @tt{@"@"}

But another option is the laternative syntax for the open/close
braces:


  @tt|{@}|

Using |{ to open the body means that only }| will be recognized as
closing the body, and commands inside should start with |@.  If that's
not enough, you can add stuff between the | and {.  For example, the
scribble syntax documentation (collects/scribblings/scribble/
reader.scrbl) has things like this:

@scribble-examples|==={
  @foo{bar baz
       blah}
  @foo{bar @baz[3]
       blah}
  @foo{bar @baz{3}
       blah}
  @foo{bar @baz[2 3]{4 5}
       blah}
}===|
