| Abstract: | Powder and single crystal X-ray diffraction studies have been performed for anhydrous nitrate complexes Rb2[Pd(NO3)4] (I) and Cs2[Pd(NO3)4] (II). Crystal data for I: a = 7.843(1) Å, b = 7.970(1) Å, c = 9.725(1) Å; β = 100.39(1)°, V = 597.9(1) Å 3, space group P21/c, Z = 2, d calc = 2.918 g/cm3; for II: a = 10.309(2) Å, b = 10.426(2) Å, c = 11.839(2) Å; β = 108.17(3)°, V = 1209.0(4) Å3, space group P21/c, Z = 4, d calc = 3.408 g/cm3. The structures are formed by isolated [Pd(NO3)4]2? complex anions and alkali metal cations. The plane-square environment of the Pd atom is formed from the oxygen atoms of the monodentate nitrate groups. The geometrical characteristics of the complex anions are analyzed. Compound II has a short contact Pd...Cs 3.252 Å. |
