Over the past few decades there has been remarkable progress in the synthesis of molecular scaffolds based on superstructured porphyrins. 1 A number of these modified porphyrins have been synthesized to mimic various aspects of the enzymatic functions of heme proteins, especially oxygen binding (myoglobin and hemoglobin), and substrate oxidation (cytochrome(More)
The structure of the title tri-fluoro-acetic acid adduct, C17H12N2O3·C2HF3O2, contains a tri-fluoro-acetic acid mol-ecule hydrogen bonded to the imine N atom of the imidazole ring of a nearly planar four-fused-ring system (r.m.s. deviatiation = 0.013 Å). The carb-oxy-lic acid group of the triflouro-acetic acid mol-ecule is twisted with respect to the mean(More)
The title complex, [CuCl(2)(C(21)H(22)N(4)O)], contains a bis-(benzimidazole) unit with a chiral bridgehead C atom that forms part of a tetra-hydro-pyrrole ring fused to one of the benzimidazoles. The chelate angle is 90.45 (9)° and the dihedral angle between the essentially planar benzimidazole fragments is 26.68 (9)°. The Cu(II) coordination geometry lies(More)
The title compound, [Co(C(10)H(10)BF(6)N(4))(C(15)H(13)BF(9)N(6))], is a polymorph of the previously reported neutral cobalt(II) complex [Stibrany & Potenza (2010 ▶). Acta Cryst. E66, m506-m507], which contains one each of the monoanionic ligands, bis-[5-methyl-3-(trifluoro-meth-yl)pyrazol-1-yl]borate (Bp) and(More)
The title compound, [Co(C(10)H(10)BF(6)N(4))(C(15)H(13)BF(9)N(6))], is a neutral Co(II) complex which contains one each of the anionic ligands, bis-(3-trifluoro-methyl-5-methyl-pyrazol-1-yl)borate (Bp) and tris-(3-trifluoro-methyl-5-methyl-pyrazol-1-yl)borate (Tp). A distorted octa-hedral coordination geometry results from ligation of an H atom, which is(More)
