Cd(BH4)2 crystallizes in the tetragonal P4_2nm space group. Cd(1) is bonded in a 8-coordinate geometry to two equivalent H(2), two equivalent H(3), and four equivalent H(1) atoms. B(1) is bonded in a tetrahedral geometry to one H(2), one H(3), and two equivalent H(1) atoms. There are three inequivalent H sites. In the first H site, H(1) is bonded in a distorted single-bond geometry to one Cd(1) and one B(1) atom. In the second H site, H(2) is bonded in a distorted single-bond geometry to one Cd(1) and one B(1) atom. In the third H site, H(3) is bonded in a single-bond geometry to one Cd(1) and one B(1) atom.
