In this paper we consider a quintom model of dark energy with a single scalar
field $T$ given by a Lagrangian which inspired by tachyonic Lagrangian in
string theory. We consider non-minimal coupling of tachyon field to the scalar
curvature, then we obtain the equation of state (EoS), and the condition
required for the model parameters when $\omega$ crosses over -1.
