چکیده
In the title compound, [Co(C(4)H(9))(C(4)H(7)N(2)O(2))(2)(C(5)H(5)N)], which was prepared as a model complex of vitamin B(12), the Co(III) atom is coordinated by a butyl group, a pyridine and two N,N'-bidentate dimethyl-glyoximate ligands in a distorted octa-hedral geometry. The bis-chelating dimethyl-glyoximate ligands, which occupy equatorial sites, are linked by strong intra-molecular O-H⋯O hydrogen bonds.

The title compound, [Co(C(14)H(14)Cl)(C(4)H(6)N(2)O(2))(2)(C(5)H(5)N)], is a model compound for the more complex cobalamines like vitamins B(12). The Co(III) atom is coordinated by a (4'-chloro-methyl-[1,1'-biphen-yl]-4-yl)methyl group, an N-bonded pyridine and two N,N'-bidentate dimethyl-glyoximate ligands in a distorted octa-hedral geometry. The glyoximate ligands exhibit intra-molecular O-H⋯...

In the title complex, [Co(C(4)H(7)N(2)O(2))(2)Cl(C(6)H(7)N)]·0.5H(2)O, the central Co(III) ion, chelated by four N atoms of the two bidenate glyoximate ligands, exhibits a slightly distorted octa-hedral geometry. The axial positions are occupied by a chloride ion and the 4-methyl-pyridine N atom. Inter-molecular O-H⋯O hydrogen bonds link the mol-ecules in the crystal via the water mol-ecules, w...

The title compound, [Co(C(4)H(7)N(2)O(2))(2)Cl(C(8)H(9)NO(2))]·CHCl(3), was synthesized as a model complex of vitamin B(12). The Co(III) cation displays an approximately octa-hedral coordination environment, being displaced by 0.0240 (15) Å from the mean plane of the four N atoms of the equatorial plane. The O-H distances in the dimethyl-glyoximate hy-droxy groups are 0.89 (6) and 1.14 (6) Å; s...
