Abstract

The X-ray crystal structure determination of a Pt(IV) nucleobase complex, trans,trans,trans-[Pt(NH3)(2)(1-MeU)(2)(H3O2)](n)(NO3)(n) .(4H(2)O)(n) (1-MeU = 1-methyluracilate-N3) is reported. The compound, obtained upon recrystallization of trans,trans,trans-[Pt(NH3)(2)(1-MeUH)(2)(OH)(2)](NO3)(2) (1-MeUH = neutral 1-methyluracil-N3) from water, crystallizes in the triclinic system, space group P-1 with two independent cations in the unit cell: a = 7.3023(8), b = 10.1470(20), c = 13.4220(20) Angstrom, alpha = 78.800(17), beta = 83.580(9), gamma = 78.930(10)degrees, V = 954.6(3) Angstrom(3), Z = 2. Description of its solid state structure as a H2O2- compound rather than a genuine mixed H2O,OH- complex is based on the presence of very short H bonds of 2.450(6) Angstrom between the oxygens of axial aqua and hydroxo ligands of adjacent Pt(IV) cations, leading to infinite chains.
