Abstract top

In the title compound, [CoCl(C2H8N2)2(C7H9N)]Cl2·0.5H2O, there are two crystallographically independent cations and anions and one water molecule in the asymmetric unit. Both CoIII ions are bonded to two chelating ethylenediamine ligands, one benzylamine molecule and one chloride ion. The crystal packing is through N-H...O, N-H...Cl and O-H...Cl interactions.

Comment top

Metal complexes find importance in the fields of biological catalysis and functions, such as in metabolism (Gray, 2003; Wohrle & Pomogailo, 2003). Cobalt complexes were also found to show biomedical applications and one such example is cancer therapy (Osinsky, 2004; Roth et al., 2002). Against this background and to ascertain the molecular conformation, the structure determination of the title compound has been carried out.

There are two crystallographically independent molecules in the asymmetric unit. The CoIII ion and the four N atoms almost lie in the same plane, whereas the other N and Cl atoms are approximately perpendicular to this plane. The Co—N and Co—Cl bond lengths are comparable with the related complexes (Lee et al., 2007; Ramesh et al., 2008). In the molecule A, the two five membered rings adopt twist conformation with the puckering parameters (Cremer & Pople, 1975) and the asymmetry parameters (Nardelli, 1983) [for the ring Co1/N1/C2/C3/N4 are: q2 = 0.416 (3) Å, φ= 90.4 (3)° and Δ2(Co1)= 0.10 (2)°; and for the ring Co1/N5/C6/C7/N8 are: q2 = 0.445 (3) Å, φ= 90.7 (3)° and Δ2(Co1)= 1.1 (2)°]. One of the five membered rings in the molecule B adopts twist conformation, whereas the other ring adopts envelope conformation [for the ring Co1'/N1'/C2'/C3'/N4' are: q2 =0.393 (2) Å, φ= 89.0 (3)° and Δ2(Co1')= 1.2 (2)°; and for the ring Co1'/N5'/C6'/C7'/N8' are: q2 = 0.443 (3) Å, φ= 281.0 (3)° and Δ2(Co1')= 11.1 (1)°].

The crystal packing is controlled by N—H···O, N—H···Cl, O—H···Cl and C—H···π types of intra and intermolecular interactions. The two intra molecular N—H···O hydrogen bonds form a S(6) ring motif. The combination of N4'-H4'D···O1, N8'-H8D···Cl3' and O1—H2W···Cl3' hydrogen bonds connects the molecule into one dimensional chain running along b–axis.

For the importance of metal complexes in the fields of biological catalysis and functions, see: Gray (2003); Wohrle & Pomogailo (2003). For the biomedical applications of cobalt complexes, see: Osinsky (2004); Roth et al. (2002). For puckering and asymmetry parameters, see: Cremer & Pople (1975); Nardelli (1983). For related structures, see: Lee et al. (2007); Ramesh et al. (2008). cis-[CoIII(en)2(BzNH2)Cl]Cl2.0.5H2O was synthesized (Bailer & Clapp, 1945) by substituting the chloride ligand with benzyl amine in trans-[Co(en)2Cl2]Cl (Bailer & Rollinson, 1946).

Experimental top

Cis-[CoIII(en)2(BzNH2)Cl]Cl2.1/2 H2O was synthesized (Bailer and Clapp, 1945), by substituting chloride ligand with benzyl amine (Bz) in trans- [Co(en)2Cl2]Cl (Bailer and Rollinson, 1946). Two grams of the cobalt(III) complex was suspended in 1 ml of water in a mortar. To this a definite amount of AnalaR benzylamine was added in drops with constant grinding to obtain a paste. A rosy red color was observed and the grinding was continued for another 1 hr to obtain a homogeneous solid mass. The paste was then allowed to stand overnight in a desicator. The Bz substituted complex was recrystallized twice using acidified water, dried and preserved in a desicator. Single crystal was grown by adding the metal complex in triply distilled water acidified with HCl and kept standing at 0°C for 2–3 weeks.

Refinement top

Nitrogen and Oxygen H atoms were refined and other H atoms were positioned geometrically (C—H=0.93–0.97 Å) and allowed to ride on their parent atoms, with 1.2Ueq(C).

Special details top

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.
