“…Their stoichiometry could be explained by assuming partial protonation of several carboxylate functions in the porphyrin tetracarboxylate moieties. [17,47] performed the insertion of osmium into 6b using a standard procedure [45] which had been modified by introducing formic acid as an additive to the carbonylating medium [48]. K 2 OsCl 6 served as the metal carrier.…”

Recent contributions to the coordination chemistry of tetraanionic water-soluble tetraarylporphyrins, namely 5,10,15,20-tetrakis(4-carboxyphenyl)porphyrin, [1]4−, 5,10,15,20-tetrakis(4-sulfonatophenyl)porphyrin, [2]4−, and 5,10,15,20-tetrakis(4-hydroxidophosphorylmethylphenyl)porphyrin, [ H 43]4−, are reported. Problems with the isolation of sodium and potassium salts of [2]4− are discussed. The tetraphosphonoporphyrin H 8[3] is precipitated as a dihydrochloride H 8[3]·2 HCl , its metal complexes H 8[3-M] as such. The synthesis of salts containing Ce and Os complexes of [1]4−, Al , Ga , In , Ge , Sn , As , Sb , Mn , Mo , W , Re , Os , and Pt complexes of [2]4−, and Ni , Cu , Zn , Pt and Os complexes of [ H 43]4− as documented in publications and doctoral theses from the Darmstadt laboratory are reviewed. Some properties of the new complex salts are reported. The results of crystal structure determinations of the potassium salt of tetrakis(4-sulfonatophenyl)porphyrinatoplatinate(II), K 8[2-Pt]2·10 DMSO ·6 H 2O· C 7 H 8, and the mixed sodium-potassium salt of tetrakis(4-sulfonatophenyl)porphyrinatoaluminate, K 2 Na [ Al ( DMSO )2( tpps 4)]·8( DMSO )·2 H 2 O , are shown.

“…79 New porphyrins include a number of complexes of the type [Os(tpp)LLЈ] (L, LЈ = various monodentate ligands) with 4-carboxy substituents on the phenyl rings; these were found to be stable in alkaline solution. 80 The first structurally characterised osmium alkoxide has been obtained in the possibly surprising milieu of porphyrin complexes. The reaction of [Os(oep)(CO)] with EtONO gave [Os(oep)(OEt)(NO)] This could be protonated by HBF 4 ؒOEt 2 to give [Os(oep)(HOEt)(NO)] ϩ , one of the first Os alcohol complexes.…”
