The relativistic four-quark equations with the open-charm and the open-strange are found in the framework of coupled-channel formalism. The dynamical mixing of the meson-meson states with the four-quark states is considered. The four-quark amplitudes including the quarks of four flavors (u, d, s, c) are constructed. The poles of these amplitudes determine the masses of tetraquarks. The mass values of the tetraquarks with the spin-parity JP=1-,2- are calculated.
