  The aim of this paper is to derive (by using two operators, representable by
a Jacobi matrix) a family of q-orthogonal polynomials, which turn to be dual to
alternative q-Charlier polynomials. A discrete orthogonality relation and a
three-term recurrence relation for these dual polynomials are explicitly
obtained. The completeness property of dual alternative q-Charlier polynomials
is also established.
