Synthesis, structural characterisation and thermal decomposition of [{Pt(dppf)(2-SPy)}{BF4}] (dppf=1, 1′- bisdiphenylphosfinoferrocene and 2-SPy=2-mercaptopyridine) - A source for a Fe-Pt containing alloy

The reaction of 2-PySK with [Pt(dppf)Cl2] [dppf=1,1′- bis(diphenylphosfinoferrocene and 2-PyS=2-mercaptopyridine] produced Pt(dppf)(2-SPy)2 (1) and its subsequent reaction with SnBu 2(BF4)2 or SnBu3(BF4) yielded [{Pt(dppf)(2-SPy)}{BF4}] (2). Compounds 1 and 2 were fully characterised by multinuclear NMR [1H, 13C{1H}, 31P{1H} and 195Pt{1H}] and 57Fe M?ssbauer spectroscopies. In addition the structure of 2 was determined by X-ray crystallographic studies, which can be summarised as follows: monoclinic P21/c, a=9.9291(9) ?, b=22.270(4) ?, c=16.919(2) ?, γ=103.6(9)°, V=3636.2(8) ?3 and Z=4. Finally, a thermal decomposition study was carried out with 2 in three different atmosphere: oxygen, nitrogen or hydrogen. The residues were characterised by X-ray powder diffraction (XRD), X-ray electron probe microanalysis (EPMA), scanning electron microscopy (SEM) and 57Fe M?ssbauer spectroscopy. The results have shown the formation of a disordered Pt1-xFex based alloy when the pyrolysis process was performed in H2, simultaneously with small amount of Fe(II) and Fe(III) phosphides. Furthermore, in oxygen and nitrogen the thermal decomposition of 2 produced metallic agglomerates of Pt dispersed in a combination of Fe(II) and Fe(III) phosphates in O2, and an intricate mixture of sulphides and phosphides in N2.
