From a nitrate solution of platinum(IV) hydroxide, (C4N2H12)[Pt(N03)6] salt containing a piperazinium cation is isolated. The salt structure is determined by X-ray crystallography. Crystallographic data are: a=15.589(1)Å, b= 12.919(1) Å, c = 9.889(9)Å, β = 08.625(4)°, space group C2/c, Z=4, ρcalc = 2.306 g/cm3. In the structure, [Pt(NO3)6]2− anions having a shape of a trigonal antiprism are organized into a 3D network by the formation of hydrogen bonds with organic cations. For a series of salts containing [Pt(NO3)6]2− and [Pt2(ώ-OH)2(NO3)8]2− anionic platinum nitrato complexes a relationship between the structure and 195Pt MAS NMR spectra is shown.
