The perselenoborates RbBSe₃ and CsBSe₃ can be prepared from the metal selenides, amorphous boron, and selenium, in the case of TlBSe₃ directly from the elements. The solid-state reactions were carried out in evacuated carbon-coated silica tubes at high temperatures. Single-crystal X-ray data were used to determine the crystal structures. Both alkali metal perselenoborates RbBSe₃ and CsBSe₃ crystallize in the monoclinic space group P2₁/c (RbBSe₃: a
