You can move one structure interactively with the mouse while the other is frozen in place ("deactivated for motion").
Model activation/deactivation can be controlled with the "A" or "Active" checkboxes in the Model Panel (this tool is under Favorites), or the checkboxes under the Command Line, or with the select command.
Or, if you are using motion commands (move, turn, etc.) instead of the mouse, there are command options to move only certain models instead of everything. However, that would require knowing the desired rotation or translation quantity and direction. It is more likely you will be using the mouse.
I hope this helps,
