Alfred Werner did his pioneering work on coordination chemistry with a compound consisting of six of this ligand coordinated to copper.
Complexes with this ligand tend to undergo substitution reactions where they simultaneously lose a halide and are de-protonated by a hydroxide, according to the SN1CB mechanism. Four of these ligands are bonded to copper in a reagent used to dissolve cellulose and named for Schweizer. A bridging pyrazine ligand, ten of these ligands, and two ruthenium atoms comprise a complex used to study inner-sphere electron transfer and named for Creutz and Taube. Alfred Werner did his pioneering work on coordination chemistry with a compound consisting of six of this ligand coordinated to copper. Two of these ligands and two chloride ligands are present in cisplatin. Because this neutral ligand is slightly stronger than water on the spectrochemical series, metal-aquo complexes are rare. For 10 points, name this compound, which is oxidized in the Ostwald process to produce nitric acid.
