Key indicatorsSingle-crystal X-ray study T = 293 K Mean '(C±C) = 0.017 A Ê R factor = 0.048 wR factor = 0.112 Data-to-parameter ratio = 14.7For details of how these key indicators were automatically derived from the article, see http://journals.iucr.org/e. # 2005 International Union of Crystallography Printed in Great Britain ± all rights reservedThe title complex, [Pt(C 5 H 4 NOS) 2 ], shows a trans-S 2 O 2 square-planar coordination geometry for the Pt II centre. The molecule self-assembles into a two-dimensional layer through weak intermolecular CÐHÁ Á ÁO/S/N interactions.

Aromatic amine N-oxide organometallic compounds: searching for prospective agents against infectious diseases

“…Platinum-mpo binding in the Pt-dppf-mpo complex agrees with the one observed in the trans-coordinated [Pt(mpo) 2 ] planar compound [mean Pt-S and Pt-O bond distances of 2.270(3) and 2.007(3) Å, respectively]. 50 Similarly, palladiummpo binding in the Pd-dppf-mpo complex agrees with that observed in [Pd(mpo) 2 ] [mean Pd-S and Pd-O bond distances of 2.242(2) and 2.043(5) Å, respectively]. 51 In both M-dppf-mpo complexes the dppf ligand shows the expected Archimedean pentagonal anti-prism conformation for the coordination around the iron in the ferrocene group, with the 5-membered Cp rings staggered to each other [Fe-C distances in the range from 2.014(6) to 2.079(6) Å for Pt-dppf-mpo and from 2.016(9) to 2.068(9) Å for Pd-dppf-mpo].…”

Nanostructured Pd Pt nanoparticles: evidences of structure/performance relations in catalytic H2 production reactions

“…Results from the analysis of the first coordination shell around the metal element for the pure Pd-MUA and Pt-MUA are reported in Table 2. The Pd-S and Pt-S contributions are at a distance typical of a binary sulfide (2.31 Å in PtS) [47] or a thiolate (2.27 Å for a Pt thiolate) [48] and indicate that about half of Pd and Pt are coordinated to a sulfur atom. Thiolate formation is expected from the synthesis in the presence of MUA, as previously reported by some of us [41], and it was corroborated by 1 H NMR results, showing broadened MUA 1 H signals in PdePt-MUA samples (Fig.…”
