Abstract (Swedish)
K2 [Pd(NO3)4] has been prepared and its crystal structure determined by use of a CAD-4 diffractometer with monochromatic Mo Kα radiation. The space group is P21/c with Z = 4; a= 7.940(2); b = 15.469(4); c = 9.453(2) Å; β = 91.10(3)°. The refinement converged to R = 0.023. The structure contains discrete complexes of [Pd(NO3)4]2− with pseudo symmetry C4. Pd coordinates four oxygen from different unidentate nitrato groups. The average Pd-O distance is 2.000(7) Å. The coordination around Pd is distorted square-planar, with Pd situated 0.139 A above the plane through the four coordinated oxygens. Similar to [Pt(NO3)4]2−, but in contrast with [Au(NO3)4]−, all four nitrato ligands are situated on the same side of the coordination plane forming a... (More)
