The electronic structure of Na2[Fe(CN)5NO]·2H2O (sodium nitroprusside: SNP) was investigated by using soft X-ray absorption (XA) spectroscopy and a configuration-interaction full-multiplet calculation for the [Fe(CN)5NO]2−cluster model.

AbstractWe bombarded $$\mbox{$\text{Cu}_{3}\text{Pd}(111)$}$$ Cu 3 Pd ( 111 ) and $$\mbox{$\text{Cu}_{3}\text{Pt}(111)$}$$ Cu 3 Pt ( 111 ) with a 2.3 eV hyperthermal oxygen molecular beam (HOMB) source, and characterized the corresponding (oxide) surfaces with synchrotron-radiation X-ray photoemission spectroscopy (SR-XPS). At $$300\,\text{K}$$ 300 K , CuO forms on both $$\mbox{$\text{Cu}_{3}\text{Pd}(111)$}$$ Cu 3 Pd ( 111 ) and $$\mbox{$\text{Cu}_{3}\text{Pt}(111)$}$$ Cu 3 Pt ( 111 ) . When we increase the surface temperature to $$500\,\text{K}$$ 500 K , $$\mbox{$\text{Cu}_{2}\text{O}$}$$ Cu 2 O also forms on $$\mbox{$\text{Cu}_{3}\text{Pd}(111)$}$$ Cu 3 Pd ( 111 ) , but not on $$\mbox{$\text{Cu}_{3}\text{Pt}(111)$}$$ Cu 3 Pt ( 111 ) . For comparison, $$\mbox{$\text{Cu}_{2}\text{O}$}$$ Cu 2 O forms even at $$300\,\text{K}$$ 300 K on Cu(111). On $$\mbox{$\text{Cu}_{3}\text{Au}(111)$}$$ Cu 3 Au ( 111 ) , $$\mbox{$\text{Cu}_{2}\text{O}$}$$ Cu 2 O forms only after $$500\,\text{K}$$ 500 K , and no oxides can be found at $$300\,\text{K}$$ 300 K . We ascribe this difference in Cu oxide formation to the mobility of the interfacial species (Cu/Pd/Pt) and charge transfer between the surface Cu oxides and subsurface species (Cu/Pd/Pt).

Isocyanoazulenes (CNAz) constitute a relatively new class of isocyanoarenes that offers rich structural and electronic diversification of the organic isocyanide ligand platform. This article considers a series of 2-isocyano-1,3-X2-azulene ligands (X = H, Me, CO2Et, Br, and CN) and the corresponding zero-valent complexes thereof, [(OC)5Cr(2-isocyano-1,3-X2-azulene)]. Air- and thermally stable, X-ray structurally characterized 2-isocyano-1,3-dimethylazulene may be viewed as a non-benzenoid aromatic congener of 2,6-dimethyphenyl isocyanide (2,6-xylyl isocyanide), a longtime “workhorse” aryl isocyanide ligand in coordination chemistry. Single crystal X-ray crystallographic {Cr–CNAz bond distances}, cyclic voltametric {E1/2(Cr0/1+)}, 13C NMR {δ(13CN), δ(13CO)}, UV-vis {dπ(Cr) → pπ*(CNAz) Metal-to-Ligand Charge Transfer}, and FTIR {νN≡C, νC≡O, kC≡O} analyses of the [(OC)5Cr(2-isocyano-1,3-X2-azulene)] complexes provided a multifaceted, quantitative assessment of the π-acceptor/σ-donor characteristics of the above five 2-isocyanoazulenes. In particular, the following inverse linear relationships were documented: δ(13COtrans) vs. δ(13CN), δ(13COcis) vs. δ(13CN), and δ(13COtrans) vs. kC≡O,trans force constant. Remarkably, the net electron withdrawing capability of the 2-isocyano-1,3-dicyanoazulene ligand rivals those of perfluorinated isocyanides CNC6F5 and CNC2F3.
