NaPd3H2 crystallizes in the orthorhombic Cmmm space group. Na(1) is bonded in a 4-coordinate geometry to two equivalent Pd(1), eight equivalent Pd(2), and two equivalent H(1) atoms. There are two inequivalent Pd sites. In the first Pd site, Pd(1) is bonded in a distorted square co-planar geometry to two equivalent Na(1) and two equivalent H(1) atoms. In the second Pd site, Pd(2) is bonded in a 8-coordinate geometry to four equivalent Na(1) and four equivalent H(1) atoms. H(1) is bonded to one Na(1), one Pd(1), and four equivalent Pd(2) atoms to form a mixture of distorted corner and edge-sharing HNaPd5 octahedra. The corner-sharing octahedra are not tilted.
