The material described by Sr2PdH4 crystallizes in the orthorhombic Pnma space group. There are two inequivalent Sr sites. In the first Sr site, Sr(1) is bonded in a 5-coordinate geometry to one H(2), two equivalent H(1), and two equivalent H(3) atoms. In the second Sr site, Sr(2) is bonded in a 9-coordinate geometry to two equivalent H(1), three equivalent H(2), and four equivalent H(3) atoms. Pd(1) is bonded in a tetrahedral geometry to one H(1), one H(2), and two equivalent H(3) atoms. There are three inequivalent H sites. In the first H site, H(1) is bonded to two equivalent Sr(1), two equivalent Sr(2), and one Pd(1) atom to form a mixture of edge and corner-sharing HSr4Pd square pyramids. In the second H site, H(2) is bonded to one Sr(1), three equivalent Sr(2), and one Pd(1) atom to form a mixture of edge and corner-sharing HSr4Pd trigonal bipyramids. In the third H site, H(3) is bonded in a 4-coordinate geometry to one Sr(1), two equivalent Sr(2), and one Pd(1) atom. is represented by the Crystallographic Information File (CIF) [CIF]
