The decays of the Higgs boson h-> Z gamma are discussed in the 3-3-1 model with beta=0. Analytic formulas for one-loop contributions was constructed used well-known general results. We will show that new particles appeared in the 3-3-1 models with beta=0 may give significant contributions to the branching ratio of the standard model-like Higgs. From numerical investigation, we will show more detailed some properties of this decay. They may be useful for comparing with the experimental result that will be detected in the future.
