I think that cguilbot is correct. The problem is in the use of scp command, not on the hosts themselves.
The "rule" is scp source

ath_to_file destination, so in you case it would be :
root@192.168.0.111:example.txt /home/<your_home_directory>/path_to_sub-dir/example.txt
Now, typically, root is not allowed to log in "over the wire" for obvious security reasons, so you may want to use a regular user for this log in or add the regular user to the sudoes file if the worst comes to worst.
Hope this helps.
