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.
