PdH6(NO)4 crystallizes in the triclinic P-1 space group. The structure is zero-dimensional and consists of one PdH6(NO)4 cluster. Pd2+ is bonded in a square co-planar geometry to four N atoms. There are two shorter (2.03 Å) and two longer (2.09 Å) Pd–N bond lengths. There are two inequivalent N sites. In the first N site, N is bonded in a trigonal planar geometry to one Pd2+ and two O2- atoms. There is one shorter (1.25 Å) and one longer (1.26 Å) N–O bond length. In the second N site, N is bonded in a distorted trigonal non-coplanar geometry to one Pd2+ and three H1+ atoms. All N–H bond lengths are 1.03 Å. There are three inequivalent H1+ sites. In the first H1+ site, H1+ is bonded in a single-bond geometry to one N atom. In the second H1+ site, H1+ is bonded in a single-bond geometry to one N atom. In the third H1+ site, H1+ is bonded in a single-bond geometry to one N atom. There are two inequivalent O2- sites. In the first O2- site, O2- is bonded in a single-bond geometry to one N atom. In the second O2- site, O2- is bonded in a single-bond geometry to one N atom.
