Diazido(2,2'-bipyridyl)dimethanolnickel(II)

H.-G. Li, S.-Y. Li and L.-J. Shao

Abstract top

The title complex, [Ni(N3)2(C10H8N2)(CH3OH)2], lies on a twofold roation axis which runs through the NiII ion and the mid-point of the bipyridine ligand. The NiII ion is coordinated in a distorted octahedral environment by two azide ligands in a trans configuration. The methanol ligands are in a cis configuration and their hydroxy groups form intramolecular O-H...(N,N) hydrogen bonds with the azide ligands.

Comment top

As has been known for some time, 2,2'-bipyridine is a good bidentate chelating ligand and the azido group a good bridging ligand. Here, we present a new six-coordinate nickel(II) complex based on 2,2'-bipyridine azido ligands.

The molecular structure of the title compound is shown in Fig. 1. The coordination environment of the NiII ion distorted octahedral, in which two sites are occupied by the two N atoms of the chelating 2,2'-bipyridine ligand and the trans positions are occupied by two N atoms of two azido ligands. Two O atoms of two methanol ligands complete the coordination. The Ni—Nbipyridine and Ni—Nazido bond lengths are basically consistant with the corresponding distances found in other nickel bipyridine azido copmplexes (Urtiaga, et al., 1995; Phatchimkun, et al., 2009; Kou, et al., 2008; Hou, 2008.).

Experimental top

A mixture of 2,2'-bipyridine, NiCl2.6H2O (1:1, molar ratio), excessive NaN3 and methanol (20 ml) was sealed in a Teflon-lined autoclave (25 ml) and heated 353 K for 12 h. Upon cooling slowly and opening the bomb, green crystals suitable for X-ray diffraction were obtained with a yield about 55% (based on 2,2'-bipyridine).

Refinement top

The H atoms bonded to C atoms were placed using the HFIX commands in SHELXL-97 (Sheldrick, 2008a), with C—H distances of 0.93 and 0.96 Å, and were allowed for as riding atoms with Uiso(H) = 1.2Ueq(C) and 1.5Ueq(C), respectively. The hydroxy H atom could not be found in a difference map but by including it using the HFIX 43 instruction in SHELXL-97 there are likely acceptors for hydrogen bonds [see Table 1].

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.
