The title compound, [Co2(O2)(CH3CN)2(C2H8N2)4](ClO4)4, consists of centrosymmetric binuclear cations and perchlorate anions. Two CoIII atoms, which have a slightly distorted octa­hedral coordination, are connected through a peroxido bridge; the O—O distance is 1.476 (3) Å. Both acetonitrile ligands are situated in a trans position with respect to the O—O bridge. In the crystal, the complex cations are connected by N—H⋯O hydrogen bonds between ethyl­endiamine NH groups and O atoms from the perchlorate anions and peroxide O atoms.

Comment top

Dioxygen complexes have been investigated in order to understand the mechanisms of oxygen metabolism such as O2 transport, storage and activation, which are essential events for life. The dioxygen cobalt complexes attract a lot of attention because of their potential use as artificial oxygen carriers (Busch et al., 1994) and industrial oxidation catalysts (Jain et al., 2003), for example: the p-xylene oxidation giving terephtalic acid and the adipic acid synthesis from cyclohexane. In many cases, reactions of cobalt (II) complexes with dioxygen proceeds, however, irreversibly resulting in formation of cobalt (III) complexes, and very often the intermediate products of such reactions appear to be binuclear cobalt (III) peroxo species. The title compound (I) was obtained as a result of reaction of cobalt (II) perchlorate in acetonitrile and ethylendiamine. The crystal structure of (I) consists of cationic dicobalt(III) µ2-peroxo complexes and perchlorate anions. The molecules are centrosymmetric. The Co (III) ions are six-coordinated, the axial positions are occupied by acetonitrile and peroxo bridge, the ethylendiamine ligands lie in the equatorial plane. The acetonitriles ligands are trans with respect to the O—O bridge. The analysis of the bond lengths and angles of (I) indicates that the coordination environment of the cobalt is slightly distorted octahedral. The bond distances Co1—N (CH3CN), Co1—O and O—O are 1.9289 (16), 1.8640 (13) and 1.476 (3) Å, respectively. The average of Co—N(en) distances is 1.9478 Å and average of O1—Co—N(en) angles is 89.80°. The bond angle O—Co—N (MeCN) is equal 177.26 (7)°. The C—N, C≡N and C—C bond lengths in the ethylenediamine and acetonitrile ligands are normal and close to the values observed in the related structures (Sliva et al., 1997; Petrusenko et al., 1997; Mokhir et al., 2002; Wörl et al., 2005).

Perchlorate anions do not form direct bonds with cobalt but they are connected to NH groups of ethylendiamine through hydrogen bonds. All of the NH groups of ethylenediamine form hydrogen bonds with either the oxygen atoms of perchlorate anions or the peroxide oxygen atoms (Table 2). A hydrogen-bonding network links the cations and anions into stacks stretching along the b axis (Fig. 2).

Experimental top

The title compound was obtained by slow diffusion of ethylendiamine vapours to the air-exposured solution, containing Co(ClO4)2 (0,1 mmol/L) in acetonitrile. The yellow-brown crystals were formed in ten days.

Refinement top

The NH2 hydrogen atoms were located from the difference Fourier map but constrained to ride on their parent atom, with Uiso = 1.5 Ueq(parent atom). Other hydrogen atoms were positioned geometrically and were also constrained to ride on their parent atoms, with C—H = 0.98–0.99 Å, and Uiso = 1.2–1.5 Ueq(parent atom). The highest peak is located 0.84 Å from atom Co1 and the deepest hole is located 0.57 Å from atom Cl1.

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.
