The first, and most likely result will be that the engine won't run any farther than the fuel in the lines will carry it, antifreeze will not burn so once it hits the injectors the engine will stop. In the tank it will pool at the bottom as it is denser than the fuel and will be the only thing the fuel pump will pick up. The problem is that you will then need to clean the entire fuel system.
If you did not start the car, you need to remove the tank and drain everything out of it. Wash it inside with gas. Reinstall the tank, add couple bottles of dry gas, fill up the tank. Start the car.
You might have to use dry gas more than once, if there is any moisture trapped within the tank (drying will not work because antifreeze takes forever to evaporate).

What happens if you ran out of gas in a 1989 Ford Tempo?
other than getting a bit of either water and or slug in your injectors it should be nothing should happen... get a carb/fuel injector cleaner in your gas tank fill up the tank with gas 89 octane or better and drive. I also put GAS antifreeze in at about half a tank and run it almost empty to clean my tank out before and after the winter which is when water can best get into your gas tank.
