In the crystal structure of the title compound, [Ni(N3)2(C12H12N2)2]·H2O, the NiII atom is situated on a twofold axis and adopts a distorted octa­hedral geometry with the two 5,5′-dimethyl-2,2′-bipyridyl (dmbpy) and the two azide ligands in a cis arrangement. The water solvent mol­ecule is disordered over two positions in a 1:1 ratio.

Comment top

It is 121 years since Blau first reported (Blau, 1888) the synthesis of 2,2'-bipyridine (bpy) and described the first metal complexes of this important ligand. Since then bpy and its derivatives have been continuously and extensively used in several aspects of coordination chemistry (Constable, 1989; Constable & Steel, 1989; Juris et al., 1988). However, up to now comparatively few X-ray crystal structures of ligand 5,5'-dimethyl-2,2'-bipyridyl (dmbpy) have been published (Albada et al., 2004; Catalan et al., 1995; Kooijman et al., 2002). In this study, we report the synthesis and characterization of the new Ni(II) complex containing both dmbpy and azido ligands. Although 52 structures containing dmbpy with metals were found in the Cambridge Structural Database (CSD; Version 5.29, November 2008 update; Allen, 2002) there was only one case (CSD refcode POMFAZ; Hou, 2008) where en is present with both NiII and 5,5'-dimethyl-2,2'-bipyridyl.

It is found that the Ni ion is coordinated by four nitrogen atoms from dmbpy and two azido nitrogen atoms, taking on a distorted octahedral geometry. The two bidentate ligands have a cis disposition around the metal ion, forming practically perpendicular planes [N2—Ni1—N2i 89.80 (7), N1—Ni1—N1i 176.19 (7)°] (symmetry codes: i -x + 2, y, -z + 1/2). The rigidity of these ligands causes the bond angles N1— Ni1—N2, 78.26 (5)° to deviate significantly from orthogonality. This causes the geometry about the NiII ion to deviate slightly from that of an ideal octahedron. The Ni(1)—N(dmbpy) bond distances in a related complex [2.0897 (13) and 2.0882 (13) Å] (Urtiaga et al., 1995) are almost the same as those found in the Ni(II) compound of [NiII(bpy)2(N3)2] [2.067 (2)–2.114 (2) Å]. Good agreement is observed between the Ni(1)–N(azido) bond distance of 2.1053 (14) Å and those reported [2.094 (2) and 2.102 (3) Å] (Urtiaga et al., 1995) for azido containing mononuclear nickel(II) complexes.

Experimental top

All chemicals were obtained commercially and used without further purification. The compound was prepared by adding a warm solution of dmbpy (0.181 g, 1.0 mmol) in methanol (15 ml) to a warming aqueous solution (10 ml) of Ni(CH3COO)2. 4H2O (0.123 g, 0.5 mmol). Afterward a solid of NaN3 (0.065 g, 1.0 mmol) was added. The green solution was slowly evaporated at room temperature and after few days, green plate-shaped crystals of [Ni(dmbpy)2(N3)2].H2O formed. They were filtered off, washed with mother liquid and air-dried. Yield ca 89%. Elemental analysis (%) found (calculated): C 54.4 (54.6), H 4.9 (4.8), N 26.3 (26.5). The IR spectrum shows the band corresponding to the asymmetric stretch of the azido ion, νas(N3), split at 2072 and 2024 cm-1. This indicates that the azido ligand is bonded asymmetrically by its two terminal N atoms.

Refinement top

The water O atom is disordered which site occupancies of 0.5 and 0.5. All non-H atoms were refined anisotropically. H atoms in aromatic were placed in idealized positions and constrained to ride on their parent atoms, with C—H distances of 0.96–1.01 Å [Uiso (H) = 1.2Ueq (C)]. H atoms of methyl groups of dmbpy were placed in calculated positions and refined with a riding model C—H = 0.96 Å.

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.
