Abstract

K2[Pt(NO3)4]·Full-size image (<1 K)H2O was prepared from ca 0.4 M solutions of platinum(II) perchlorate in perchloric acid by addition of KHCO3 and KNO3. Its crystal structure was determined from X-ray intensity data collected with a CAD-4 diffractometer. Monochromatic MoKα-radiation was used. The space group is I4/m with Z = 4; a = 7.5277(4) and c = 20.470(3) Å. The refinement converged to R = 0.036. The structure contains discrete complexes, [Pt(NO3)4]2−, with symmetry C4. Pt coordinates four O from different unidentate nitrato groups. The PtO distance is 2.010(5) Å. The coordination around Pt is distorted square-planar, with Pt situated 0.14 Å above the plane formed by four O, so that a very flat, square pyramid is formed. Two such pyramids on each side of the mirror plane are packed together with their bases facing each other. The closest OO distance between them is 3.29(1) Å and the PtPt distance is 3.590(1) Å. The potassium ions are located between the pairs of complexes so that a three-dimensional packing of K+ and 2×[Pt(NO3)4]2− is formed.
