Sufficient conditions for constructing a set of solutions of the Toda lattice are analyzed. First, under certain conditions the invariance of the spectrum of is established in the complex case. Second, given the tri-diagonal matrix defining a Toda lattice solution, the dynamic behavior of zeros of polynomials associated to is analyzed. Finally, it is shown by means of an example how to apply our results to generate complex solutions of the Toda lattice starting with a given solution.
