Tris(1,10-phenanthroline)nickel(II) dichromate tetrahydrate

H.-X. Liu

Abstract top

The asymmetric unit of the title compound, [Ni(C12H8N2)3][Cr2O7]·4H2O, contains one cation, one anion and four water molecules, three of which are disordered over two sites with equal occupancies. In the cation, the metal centre is coordinated by six N atoms from three 1,10-phenanthroline ligands in a distorted octahedral geometry. The [Cr2O7]2- anion exhibits a staggered conformation. The crystal packing is stabilized by intermolecular O-H...O hydrogen bonds and [pi]-[pi] interactions, evidenced by short distances of 3.531 (5) Å between the centroids of aromatic rings.

Comment top

Metal complexes containing the chromate(VI) or dichromate(VI) anions, CrO42- or Cr2O72-, attract attention owing to their various properties (Ejsmont et al., 2002). 1,10-Phenanthroline (phen), which is the parent of an important class of chelating agents, has been widely used in the construction of supramolecular architectures. Some Nickel phenanthroline complexes have been synthesized and reported (Suescun et al., 1999; Wang et al., 2007; Wiehl et al., 2008). As a continuation of these studies, I now report the crystal structure of the title complex.

The title structure (Fig. 1) is build up of one Ni atom, three coordination phenanthroline ligand, dichromate and four free water molecules. Ni center is coordinated with six N atoms from three 1,10-phenanthroline ligands, presenting a distorted octahedral geometry. The Ni—N and Cr—O bond lengths are in the ranges 2.064 (7)–2.115 (7) and 1.583 (7)–1.786 (6) Å, respectively. The bond angles O—Cr—O, N—Ni—N are in the ranges of 107.1 (3)–111.4 (4) and 78.6 (3)–168.9 (3) °, respectively. The mean Cr—O bond lengths and O—Cr—O bond angles are similar to the reported earlier (Ejsmont et al., 2002).

The crystal packing is stabilized by intermolecular O—H···O hydrogen bonds (Table 1) and π-π interactions evidenced by short distance of 3.531 (5) Å between the centroids of aromatic rings.

Experimental top

All commercially obtained reagent-grade chemicals were used without further purication. A mixture of NiCl2 (0.1 mmol, 0.014 g), 1,10-phenanthroline (0.1 mmol, 0.018 g), K2CrO4 (0.1 mmol, 0.019 g) and H3BO3 (0.1 mmol, 0.006 g) were added into 20 ml water with 20%(v/v) ethanol and heated for 12 h at 140 °. The solution was obtained by filtration after cooling the reaction to room temperature. Yellow block single crystals suitable for X-ray measurements were obtained after a few weeks.

Refinement top

All H atoms were geometrically positioned (C—H 0.93 Å, O—H 0.85 Å) and refined using a riding model, with Uiso (H) =1.2–1.5 Ueq of the parent atom.

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.
