The crystal structure described by Eu(BH4)2 crystallizes in the orthorhombic Pbcn space group. Eu(1) is bonded in a 12-coordinate geometry to two equivalent H(1), two equivalent H(4), four equivalent H(2), and four equivalent H(3) atoms. B(1) is bonded in a tetrahedral geometry to one H(1), one H(2), one H(3), and one H(4) atom. There are four inequivalent H sites. In the first H site, H(4) is bonded in a single-bond geometry to one Eu(1) and one B(1) atom. In the second H site, H(1) is bonded in a distorted single-bond geometry to one Eu(1) and one B(1) atom. In the third H site, H(2) is bonded in a single-bond geometry to two equivalent Eu(1) and one B(1) atom. In the fourth H site, H(3) is bonded in a single-bond geometry to two equivalent Eu(1) and one B(1) atom. is represented by the CIF file [CIF]
