The mononuclear nickel title complex (acetonitrile-κN){N-benzyl-N,N′,N′-tris[(6-methylpyridin-2-yl)methyl]ethane-1,2-diamine}nickel(II) bis(tetrafluoridoborate), [Ni(C₃₀H₃₅N₅)(CH₃CN)](BF₄)₂, was prepared from the reaction of Ni(BF₄)₂·6H₂O with N-benzyl-N,N′,N′-tris[(6-methylpyridin-2-yl)methyl]ethane-1,2-diamine (bztmpen) in acetonitrile at room temperature. With an open site occupied by the acetonitrile molecule, the nickel(II) atom is chelated by five N-atom sites from the ligand and one N atom from the ligand, showing an overall octahedral coordination environment. Compared with analogues where the 6–methyl substituent is absent, the bond length around the Ni²⁺ cation are evidently longer. Upon reductive dissociation of the acetronitrile molecule, the title complex has an open site for a catalytic reaction. The title complex has two redox couples at −1.50 and −1.80 V (versus F_c^+/0) based on nickel. The F atoms of the two BF₄⁻ counter-anions are split into two groups and the occupancy ratios refined to 0.611 (18):0.389 (18) and 0.71 (2):0.29 (2).

Keywords: crystal structure; nickel; poly-pyridine-diamine; electro-catalyst.

1. Chemical context

Nickel complexes with polypyridine–amine ligands are of great interest in catalytic reactions. For example, nickel complexes containing N5-pentadentate ligands with different amine-to-pyridine ratios have been studied for electrochemical H₂ production in water at pH = 7 and the complex with a diamine–tripyridine ligand displays a TON (turn-over number) of up to 308000 over 60 h electrolysis at −1.25 V vs the standard hydrogen electrode (SHE), with a Faradaic efficiency of 91% (Zhang et al., 2014 ). The nickel-based complex Ni–PY₅ {PY₅ = 2,6-bis[1,1-bis(2-pyridyl)ethyl]pyridine} has been found to act as an electro-catalyst for oxidizing water to dioxygen in aqueous phosphate buffer solutions (Wang et al., 2016 ). The rate of water oxidation catalyzed by the Ni–PY₅ complex is enhanced remarkably by the proton-acceptor base HPO₄²⁻, with a rate constant of 1820 M⁻¹ s⁻¹. A stable configuration is important for the stability of a catalyst. In the title complex, the Ni²⁺ cation is chelated by five N-atom sites, so the configuration is stable. With the reductive dissociation of acetonitrile, the title complex would give an open site for a catalytic reaction. Herein, we describe the crystal structure and electrochemical properties of the title complex.

2. Structural commentary

In the title complex (Fig. 1), the coordination sphere of the nickel(II) atom adopts a normal octahedral geometry. The Ni²⁺ cation lies almost in the equatorial plane. One pyridine nitrogen atom (N1) and two amino nitrogen atoms (N2, N3) as well as the nitrogen atom of an acetonitrile ligand (N4) form the equatorial plane. The latter can easily be dissociated from nickel. The axial positions are occupied by two pyridine nitrogen atoms (N5, N6). The Ni—N bond lengths for the two axial pyridine–nitrogen atoms [Ni—N5 = 2.209 (3) and Ni—N6 = 2.187 (3) Å] are significantly longer than that for the other four nitrogen atoms [Ni—N1 = 2.151 (3), Ni—N2 = 2.082 (3), Ni—N3 = 2.188 (2), Ni—N4 = 2.061 (3) Å]. The presence of the 6-methyl substituent hinders the approach of the pyridine group to the Ni²⁺ core. A a result of the steric hindrance from the methyl substituent, the three atoms N5, Ni1 and N6 are not completely linear in the axial direction, with a contact angle of 170.89 (9)°. Two intramolecular C—H⋯N contacts occur (Table 1).

3. Electrochemical commentary

Generally, the reduction of a metal complex is accompanied by the dissociation of the ligand, or the weakest ligand if more than one ligand is present, which could induce the appearance of an open site for a catalytic reaction (Knoll et al., 2014 ; Johnson et al., 2016 ). The introduction of o-methyl in the title complex is in favor of the dissociation of acetonitrile. On the cathodic scan under Ar, the title complex features one reversible couple at −1.50 V and one half-reversible couple at −1.80 V (vs F_c^+/0) based on nickel, assigned to Ni^II/I and Ni^I/0 respectively (Fig. 2). The third couple at −2.15 V could be assigned to the reduction of pyridine. The free ligand bztmpen itself is electrochemically silent in the potential range (Fig. 3). The coordination with nickel leads to a positive shift of the reduction on pyridine. The good reversibility of the couple indicates a negligible change in the configuration of the title complex after one electron reduction. The second reduction might result in a change of the configuration. Analogues in the absence of o-methyl show only one redox couple more negative than −1.50 V (vs F_c^+/0; Zhang et al., 2014). The positive shift of the first redox couple for the title complex results from the weaker electron-donating ability of the pyridine ligands, which are farther from the nickel core. The electrochemical properties of these analogues are consistent with the differences shown in the structure.

4. Supramolecular features

In the title crystal, no classical hydrogen bonds have been found. Weak C—H⋯F contacts (Table 1) link the components into a three-dimensional network. The crytal paacking is illustrated in Fig. 4.

5. Database survey

There are three published nickel complexes with poly-pyridine groups (Shi et al., 2015 ; Zhang et al., 2014; Wang et al., 2016), but to the best of our knowledge, the title compound has not been reported previously. The nickel complex with N,N,N′,N′-tetra(2-pyridylmethyl)ethylenediamine (tpen) adopts a normal octahedral geometry (Shi et al., 2015). In the Ni²⁺(tpen) complex, the Ni—N1, Ni—N2, Ni—N3, Ni—N4, Ni—N5 and Ni—N6 bonds [2.106 (3), 2.099 (3), 2.114 (3), 2.086 (3), 2.094 (3) and 2.120 (2) Å, respectively] are shorter than the corresponding bond lengths in the title complex. Among the earliest reports, the nickel complex with N-benzyl-N,N′,N′-tris(2-pyridylmethyl)ethylenediamine (bztpen) ligand is most similar to the title complex (Zhang et al., 2014). Under reductive conditions, Ni²⁺(bztpen) displays a high activity on electro-catalytic water reduction. The title complex possesses a higher steric hindrance than Ni²⁺(bztpen), which affects evidently the bond lengths, especially in the axial direction. The bonds lengths in the title complex [Ni—N5 = 2.209 (3), Ni—N6 = 2.187 (3) Å] are longer than those in Ni²⁺(bztpen) [Ni—N5 = 2.149 (3), Ni—N6 = 2.096 (3) Å]. The nickel complex with a PY₅ ligand {PY₅ = 2,6-bis[1,1-bis(2-pyridyl)ethyl]pyridine} displays a similar configuration to the title complex, but the labile ligand is at the axial site (Wang et al., 2016). Ni²⁺(PY₅) has been found to act as an electro-catalyst for oxidizing water to dioxygen in an aqueous phosphate buffer solution.

6. Synthesis and crystallization

The tripyridine-diamine ligand N-benzyl-N,N′,N′-tris[(6-methylpyridin-2-yl)methyl]ethane-1,2-diamine (bztmpen) was prepared according to literature procedures (Zhang et al., 2013 ), ¹H NMR (CDCl₃, 600 MHz): δ 7.44 (m, 4H), 7.25 (m, 6H), 6.96 (m, 4H), 3.74 (s, 6H), 3.58 (s, 2H), 2.75 (d, 4H), 2.49 (s, 9H). ESI–MS: calculated for [M + H]⁺: m/z 466.63; found: 466.27.

Preparation of [Ni(bztmpen)(CH₃CN)](BF₄)₂. Compound Ni(BF₄)₂·6H₂O (0.16 g, 0.5 mmol) was added to an acetonitrile solution (5 mL) of bztmpen (0.2 g, 0.5 mmol). The mixture was stirred at room temperature for 6 h. The purple solution was then transferred to tubes, which were placed in a flask containing ether. Block-shaped blue crystals were obtained in a yield of 85% (0.25 g). Analysis calculated for C₃₂H₃₈B₂F₈N₆Ni (%): C, 50.01; H, 5.18; N, 11.37; found: 50.01; H, 5.19; N, 11.36; MS (TOF–ES): m/z = 282.6341 {[M−2BF₄⁻]/2}⁺, 599.3015 [M – 2BF₄⁻ + Cl⁻]⁺.

7. Refinement

Crystal data, data collection and structure refinement details are summarized in Table 2. The F atoms of the two BF₄⁻ counter-anions were split into two groups and the occupancies refined to 0.611 (18)/0.389 (18) and 0.71 (2)/0.29 (2). The hydrogen atoms were refined in a riding mode with C—H = 0.93–0.97 Å and U_iso(H) = 1.2U_eq(C).

Special details top

Geometry. All esds (except the esd in the dihedral angle between two l.s. planes) are estimated using the full covariance matrix. The cell esds are taken into account individually in the estimation of esds in distances, angles and torsion angles; correlations between esds in cell parameters are only used when they are defined by crystal symmetry. An approximate (isotropic) treatment of cell esds is used for estimating esds involving l.s. planes.
