The bound states of $B^*\\bar{B}^*$ with $I(J^{PC})=1(0^{++}),~1(1^{+-}),~0(2^{++})$ and $B\\bar{B}^*$ with isospin $I=1$, or $0$ are obtained in color-singlet-singlet channel. If considering the coupling of color channels, apart from the deep bound states appear in $[b\\bar{q}]^{(*)}[q\\bar{b}]^{(*)}$ scenario, a bound state $[c\\bar{q}]^*[q\\bar{c}]^*$ with $I(J^{PC})=1(0^{++})$ is also formed.
