We provide a categorification of (mathfrak {q}(2))-crystals on the singular (mathfrak {gl}_{n})-category ({mathcal O}_{n}). Our result extends the (mathfrak {gl}_{2})-crystal structure on ( ext {Irr} ({mathcal O}_{n})) induced from the work of Bernstein-Frenkel-Khovanov. Further properties of the ({mathfrak q}(2))-crystal ( ext {Irr} ({mathcal O}_{n})) are also discussed.
