The Cauchy initial value problem for the defocusing quintic nonlinear Schrodinger equation in two dimensions with general data in the critical space (H)over dot(1/2)(R-2) is considered. It is shown that if a solution remains bounded in (H)over dot(1/2)(R-2) in its maximal interval of existence, then the interval is infinite and the solution scatters.
