Abstract top

The title complex, [Co(C5H2N2O4)(C14H8N4)2]·2H2O, features a slightly distorted octahedral geometry for Co due to the sterical requirements of the orotic acid and pyrazino[2,3-f][1,10]phenanthroline ligands. Intermolecular hydrogen bonding between the uncoordinated water molecules and the ligand stablizes the structure of the complex.

Comment top

Orotic acid is an important pyrimidine derivative as the effective precursor in the biosythesis of the pyrimidine base of nucleic acids in living organisms and plays a unique role in bioinorganic and pharmaceutical chemistry (Lieberman et al., 1955). Aside from the biological interest, orotic acid is also interesting in coordination chemistry (Lalioti et al., 1998). In this contribution, the title compound (I) was synthesized and its crystal structure determined (Fig. 1 and Table 1). The central Co is coordinated by five nitrogen atoms (four from pyrazino[2,3-f][1,10]phenanthroline ligand and one from orotic acid ligand) and one carboxylate oxygen from the orotic acid ligand,yielding a slightly distorted octahedral coordination geometry. The geometric parameters are in good agreement with those found in literature (Darensbourg et al., 1998). The intermolecular hydrogen bonding between the uncoordinated water molecules and the ligand stablizes the structure of the complex (Fig. 2).

Experimental top

The orotic acid (Lancaster, 98%) and solvents were commercially available, and they were used without further purification. The orotic acid (0.035 g, 0.2 mmol) CoCl2 6H2O (0.047 g, 0.2 mmol) and pyrazino[2,3-f][1,10]phenanthroline were added to 40 ml EtOH-water(1:2 V:V) and heated to 353 K and stirred for 20 min.A few drops of ammonia were added to adjust the pH value to about 6 and then the resulting mixture was filtered. Orange single crystals were obtained after a few days. Yield, 0.096 g, 75%. m.p. 450–452 K.

Analysis found: C 55.50, H 3.14, N 19.58, O 13.42%; C33H22N10O6Co requires: C 55.55, H 3.11, N 19.63, O 13.45%.

Refinement top

All H atoms were initially located in diffrence Fourier map. The C, O and N bound H atoms were then constrained to an ideal geometry, with C—H = 0.93 Å and refined as riding with Uiso(H) = 1.2Ueq(C-aromatic) and with the O—H = 0.8494 - 0.8512 Å, N—H = 0.8321 Å and refined as riding with Uiso(H) = 1.2Ueq(O, N).

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.
