An introduction of a new subclass of bi-univalent functions involving Sakaguchi type functions defined by (p, q)-Derivative operators using Gegenbauer polynomials have been obtained. Further, the bounds for initial coefficients vertical bar a(2)vertical bar, vertical bar a(3)vertical bar and Fekete Szego inequality have been estimated.
