**Abstract: **

In this present paper, as applications of the post-quantum calculus known as the (p,q)-calculus, we construct a new class D_{p,q}^{k} of bi-univalent functions of complex order deﬁned in the open unit disk. Coeﬃcients inequalities and several special consequences of the results are obtained.

**Keywords: **

Coeﬃcient bounds, Bi-univalent functions, Quasi-subordination, q-calculus, (p,q)-derivative operator.
