The synthesis of the title complex was carried out by mixing Co(ClO4)2.6H2O (0.1 mmol, 36.6 mg), 4-chloro-pyridine (0.2 mm mol, 22.8 mg) and the Schiff-base ligand (0.1 mmol, 26.8 mg) in methanol. After the mixture was stirred for about half an hour at room temperature in air, it was filtered, and the filtrate was allowed to partially evaporate for one week to produce crystals suitable for X-ray diffraction with an yield about 51%. Anal. Calcd for C27H26Cl3CoN4O7: C, 47.42; H, 3.83; N, 8.19. Found: C, 47.54; H, 3.75; N, 8.095. Main IR bands (cm-1): 3020 (s, C—H),1618 (m, C=N), 1093 (s, Cl=O).
All the H atoms bonded to the C atoms were placed using the HFIX commands in SHELXL-97 with C—H distances of 0.93 and 0.96 Å, and were allowed for as riding atoms with Uiso(H) = 1.2Ueq(C) or Uiso(H) = 1.5Ueq(C), respectively. For the H atoms bonded to O atom, it was found from difference Fourier maps with the bond lengths restrained to 0.82 Å, and was allowed for as riding atoms with Uiso(H) = 1.5Ueq(O).
Tetradentate Schiff-base ligands, due to their excellent chelating ability for metal atoms, have been widely used to synthsize transition metal complexes. Here, we report the
of a CoIII complex based on tetradentate Schiff base ligand N,N'-bis(salicylidene)-1,2-diphenyl-1,2-ethanediamine.The cation structure of the title complex is shown in Fig. 1. The CoIII ion is six coordinated by a N4O2 unit, in which the four equational sites are occupied by two N atoms and two O atoms from the tetradentate Schiff base ligand and the two axial sites are occupied by the N atoms of two 4-chloro-pyridine ligands, therefore forming a slightly distorted octahedral coordination environment. The Co—O, Co—NSchiff-base and Co—Npyridinebond lengths are 1.891 (2), 1.898 (2),1.892 (3), 1.897 (3), 1.977 (3) and 1.995 (3)A%, respectively, which are all comparable to the corresponding bond lengths found in the previously reported CoIII Schiff-base complexes (Chen, 2008; Kitaura, et al., 1987; Shi, et al., 1995; Zhou, 2009).

Geometry. All e.s.d.'s (except the e.s.d. in the dihedral angle between two l.s. planes) are estimated using the full covariance matrix. The cell e.s.d.'s are taken into account individually in the estimation of e.s.d.'s in distances, angles and torsion angles; correlations between e.s.d.'s in cell parameters are only used when they are defined by crystal symmetry. An approximate (isotropic) treatment of cell e.s.d.'s is used for estimating e.s.d.'s involving l.s. planes. |
Refinement. Refinement of F2 against ALL reflections. The weighted R-factor wR and goodness of fit S are based on F2, conventional R-factors R are based on F, with F set to zero for negative F2. The threshold expression of F2 > σ(F2) is used only for calculating R-factors(gt) etc. and is not relevant to the choice of reflections for refinement. R-factors based on F2 are statistically about twice as large as those based on F, and R- factors based on ALL data will be even larger. |

Tetradentate Schiff-base ligands, due to their excellent chelating ability for metal atoms, have been widely used to synthsize transition metal complexes. Here, we report the crystal structure of a CoIII complex based on tetradentate Schiff base ligand N,N'-bis(salicylidene)-1,2-diphenyl-1,2-ethanediamine.
The cation structure of the title complex is shown in Fig. 1. The CoIII ion is six coordinated by a N4O2 unit, in which the four equational sites are occupied by two N atoms and two O atoms from the tetradentate Schiff base ligand and the two axial sites are occupied by the N atoms of two 4-chloro-pyridine ligands, therefore forming a slightly distorted octahedral coordination environment. The Co—O, Co—NSchiff-base and Co—Npyridinebond lengths are 1.891 (2), 1.898 (2),1.892 (3), 1.897 (3), 1.977 (3) and 1.995 (3)A%, respectively, which are all comparable to the corresponding bond lengths found in the previously reported CoIII Schiff-base complexes (Chen, 2008; Kitaura, et al., 1987; Shi, et al., 1995; Zhou, 2009).
