In the present calculations, two structures, meson-meson [$\\bar{Q}Q$][$\\bar{Q}Q$] and diquark-antidiquark [$QQ$][$\\bar{Q}\\bar{Q}$] ($Q$ = $c$ or $b$), and their mixing, along with all possible color, spin configurations are considered. The calculations suggest that no bound state can be formed for $bb\\bar{c}\\bar{c}$ and $bc\\bar{b}\\bar{c}$ systems. However, resonances are possible because of the color structure.
