We study merging mechanism for the creation of complex networks in several models. In the evolution process for the models, vertices merge together in the specified distance, preferential way or randomly. The distance of the two nodes are important parameter for some of these models. We observe that only for the model that merging is related to the fixed distance of the nodes the structure of the network is not scale free and the other models belong to the category of the scale free networks with the exponent less or equal 2.
