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