To a solution containing N,N-bis(2-hydroxybenzyl)ethane-1,2-diamine (1.52 g, 5 mmol) and ethanol (20 ml), a solution of cerium nitrate (1.09 g, 5 mmol) and methanol (10 ml) was added with stirring for 3 h at 333–343 K; the solid obtained was filtered off, washed successively with ethanol, and dried at room temperature. Dark red crystals of (I) suitable for X-ray structure analysis were obtained by slow evaporation of a chloroform–ethanol (1:2) solution containing the product over a period of one week.
All H atoms were located in difference Fourier maps and then treated as riding atoms, with C—H distances of 0.93 Å (aryl), 0.97 Å (methylene), 0.98 Å (methine), N—H distances of 0.91 Å (amine), and with Uiso(H) = 1.2Ueq(C,N) (aryl, methylene, methine, amine).
Some CeIVcomplexs has been shown to hydrolyze DNA effectively at a reasonable rate (Franklin, 2001; Williams et al.,1999; Takasaki & Chin, 1994; Branum et al., 2001; Komiyama et al., 1999). We have reported recently the crystyl structure of a CeIV complex (Liu et al., 2007). As part of our study of the CeIVcomplexes with the diamine derives, We report here the crystal structure of a new CeIVcomplex, bis[N,N'-bis(2-oxidobenzyl)ethane-1,2-diamine-κ2N,N',O,O'] cerium(IV) chloroform disolvate, (I).
Compound (I) crystallizes in the space group P21/n, and the asymmetric unit contains a title complex and one chloroform molecule, which are linked by one N—H···Cl and one C—H···O hydrogen bonds into a dimeric structure (Table 2 and Fig. 1). The CeIV atom is coordinated by four O atoms and four N atoms from two tetradentate ligand, N,N'-(2-oxidobenzyl)ethane-1,2-diamine, forming a complex eight-coordinated stereochemistry geometry (Fig. 1). Two least-squares planes are defined by the atoms Ce1/O1/O2/N1/N2 and Ce1/O3/O4/N3/N4, and which are approximately planar, the maximum deviation are -0.079 (3) Å for N2 and -0.118 (3) Å for N3, respectively. The dihedral angle between the two least-squares planes are 89.23 (9)°. The average Ce—O and Ce—N distance are 2.192 (4) Å and 2.620 (4) Å, these values are approximately similar to the CeIV complexes reported [2.199 (4)Å and 2.624 (4) Å; Liu et al., 2007], and the bond angles ranges around CeIV atom are O—Ce—O of 95.1 (2)° - 149.1 (1)°, N—Ce—N of 66.5 (1)° - 135.3 (1)° (see in Table 1). The crystal structure of (I) is stabilized by two C—H···π, one N—H···Cl and one C—H···Cl interactions (Table. 2).

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. |

Some CeIVcomplexs has been shown to hydrolyze DNA effectively at a reasonable rate (Franklin, 2001; Williams et al.,1999; Takasaki & Chin, 1994; Branum et al., 2001; Komiyama et al., 1999). We have reported recently the crystyl structure of a CeIV complex (Liu et al., 2007). As part of our study of the CeIVcomplexes with the diamine derives, We report here the crystal structure of a new CeIVcomplex, bis[N,N'-bis(2-oxidobenzyl)ethane-1,2-diamine-κ2N,N',O,O'] cerium(IV) chloroform disolvate, (I).
Compound (I) crystallizes in the space group P21/n, and the asymmetric unit contains a title complex and one chloroform molecule, which are linked by one N—H···Cl and one C—H···O hydrogen bonds into a dimeric structure (Table 2 and Fig. 1). The CeIV atom is coordinated by four O atoms and four N atoms from two tetradentate ligand, N,N'-(2-oxidobenzyl)ethane-1,2-diamine, forming a complex eight-coordinated stereochemistry geometry (Fig. 1). Two least-squares planes are defined by the atoms Ce1/O1/O2/N1/N2 and Ce1/O3/O4/N3/N4, and which are approximately planar, the maximum deviation are -0.079 (3) Å for N2 and -0.118 (3) Å for N3, respectively. The dihedral angle between the two least-squares planes are 89.23 (9)°. The average Ce—O and Ce—N distance are 2.192 (4) Å and 2.620 (4) Å, these values are approximately similar to the CeIV complexes reported [2.199 (4)Å and 2.624 (4) Å; Liu et al., 2007], and the bond angles ranges around CeIV atom are O—Ce—O of 95.1 (2)° - 149.1 (1)°, N—Ce—N of 66.5 (1)° - 135.3 (1)° (see in Table 1). The crystal structure of (I) is stabilized by two C—H···π, one N—H···Cl and one C—H···Cl interactions (Table. 2).
