Murray and Federer are joined by US Open champion Juan Martin del Potro and Spain’s Fernando Verdasco in Group A at the 02 Arena in London.
Group B features Rafael Nadal, Novak Djokovic, Nikolay Davydenko and Robin Soderling.
Soderling initially failed to qualify for the prestigious eight-man event but was handed a place when Wimbledon finalist Andy Roddick was forced to pull out through injury.
