Crystal structure of di-μ-hydroxido-κ4 O:O-bis[bis(acetylacetonato-κ2 O,O′)cobalt(III)]
The dinuclear title complex, [Co2(C5H7O2)4(μ-OH)2] or [Co(acac)2(μ-OH)]2, where acac is acetyl-acetonate, is centrosymmetric with half of the mol-ecule per asymmetric unit. The mol-ecular structure is a dimer of octa-hedrally coordinated Co(III) atoms with four O atoms from two chelating acac ligands and two O atoms from bridging hydroxide ligands. The crystal packing features weak C-H⋯O inter-...
متن کاملDinuclear cobalt(II) and cobalt(III) complexes of bis-bidentate napthoquinone ligands.
The combination of bridging bis-bidentate redox-active ligands derived from 3,3-bis-2-hydroxy-1,4-naphthoquinone (bhnqH2), ancillary ligands based on tris(2-pyridylmethyl)amine (tpa) and cobalt salts has afforded a new family of dinuclear cobalt complexes. Compounds of the complexes [Co2(bhnq)(tpa)2](2+) (1), [Co2(bhnq)(Metpa)2](2+) (2), [Co2(bhnq)(Me2tpa)2](2+) (3) [Co2(bhnq)(Me3tpa)2](2+) (4)...
متن کاملTetraammine(carbonato-κ2 O,O′)cobalt(III) perchlorate
In the title complex, [Co(CO3)(NH3)4]ClO4, both the cation and anion lie on a mirror plane. The Co(III) ion is coordinated by two NH3 ligands and a chelating carbonato ligand in the equatorial sites and by two NH3 groups in the axial sites, forming a distorted octa-hedral geometry. In the crystal, N-H⋯O hydrogen bonds connect the anions and cations, forming a three-dimensional network.
متن کاملTris(3-nitropentane-2,4-dionato-κ2 O,O′)cobalt(III)
The structure of the title compound, [Co(C(5)H(6)NO(4))(3)], consists of a Co(III) ion octahedrally coordinated by three bidentate 3-nitro-pentane-2,4-dionate ligands. The complex was prepared via the nitration of tris-(2,4-penta-nedionato-κ(2)O,O')cobalt(III) with a solution of copper(II) nitrate in glacial acetic acid. The central C atom and the nitro group of one 3-nitro-pentane-2,4-dionate ...
متن کاملBis(diethylenetriamine)cobalt(III) hexachloridoindate(III)
The title compound, [Co(C(4)H(13)N(3))(2)][InCl(6)], was synthesized under hydro-thermal conditions. In the cation, the Co-N bond lengths lie in the range 1.967 (2)-1.9684 (15) Å. In the anion, the In(III) atom is coordinated by six Cl atoms resulting in a slightly distorted octa-hedral geometry. Both metal atoms are located on special positions of site symmetry 2/m. Furthermore, one Cl atom an...
