We study dynamically generated resonances by interactions between vector mesons including their coupling to channels of pseudoscalar mesons within coupled-channel approach. Both vector and pseudoscalar mesons are considered as t-channel exchanged mesons for calculating interactions between vector mesons. Analogous to as a dynamically generated state, there is an as a coupled channel dynamically generated state near threshold. The channels involved are . This mainly decays to , and . This pole is much tied to the coupled channel effect. If we turn off either or , the pole disappears. In addition, it is found that may also be dynamically generated by interactions due to and exchange.
