Materials Data on H12PdC4(NO5)2 by Materials Project
Pd(CO2)4(NH4)2(H2O)2 crystallizes in the monoclinic P2_1/c space group. The structure is zero-dimensional and consists of four ammonium molecules, four water molecules, and two Pd(CO2)4 clusters. In each Pd(CO2)4 cluster, Pd4+ is bonded in a square co-planar geometry to four O2- atoms. There are two shorter (2.03 Å) and two longer (2.05 Å) Pd–O bond lengths. There are two inequivalent C+2.50+ sites. In the first C+2.50+ site, C+2.50+ is bonded in a bent 120 degrees geometry to two O2- atoms. There is one shorter (1.25 Å) and one longer (1.30 Å) C–O bond length. In the second C+2.50+ site, C+2.50+ is bonded in a bent 120 degrees geometry to two O2- atoms. There is one shorter (1.24 Å) and one longer (1.30 Å) C–O bond length. There are four inequivalent O2- sites. In the first O2- site, O2- is bonded in a distorted bent 120 degrees geometry to one Pd4+ and one C+2.50+ atom. In the second O2- site, O2- is bonded in a single-bond geometry to one C+2.50+ atom. In the third O2- site, O2- is bonded in a single-bond geometry to one C+2.50+ atom. In the fourth O2- site, O2- is bonded in a distorted bent 120 degrees geometry to one Pd4+ and one C+2.50+ atom.
