Bis(2-dimethylamino-1,10-phenanthroline-[kappa]2N,N')bis(thiocyanato-[kappa]N)nickel(II) methanol disolvate

Abstract top

In the title complex, [Ni(NCS)2(C14H13N3)2]·2CH3OH, the NiII atom lies on a crystallographic twofold rotation axis and is in a slightly distorted octahedral NiN6 coordination environment. The crystal structure is stabilized by a combination of weak [pi]-[pi] stacking interactions between symmetry-related 1,10-phenanthroline ligands [centroi-centroid distance between benzene rings = 3.5936 (18) Å] and weak O-H...S, C-H...O and C-H...S hydrogen bonds between methanol and complex molecules.

Comment top

The derivatives of 1,10-phenanthroline play a pivotal role in the area of modern coordination chemistry (Zhang et al. 2006) and a number of complexes have been reported with derivatives as ligands (Liu et al. 2008). Here we report the crystal structure of the title complex, (I), formed using 2-(dimethyl)amine-1,10-phenanthroline as a ligand.

The molecular structure of (I) is shown in Fig. 1. In the mononuclear complex, atom Ni1 is in a slightly distorted octahedral geometry (Table 1). There is a single π-π stacking interaction involving symmetry related 1,10-phenanthroline ligands, with the the relevant distances being Cg1···Cg1i = 3.5936 (18) Å and Cg1···Cg1iperp = 3.449 Å; α = 0.00° [symmetry code: (i) 1-x,-y,-z; Cg1 is the centroid of the C4—C9 ring; Cg1···Cg1perp is the perpendicular distance from ring Cg1 to ring Cg1i; α is the dihedral between the two ring planes]. In addition, the crystal structure contains weak O—H···S, C—H···O and C—H···S hydrogen bonds between methanol molecules and complex molecules [Fig. 2 and Table 2]. In addition to the π-π stacking interactions and the hydrogen bonds there is relatively close contact between the H atom of the hydroxyl and symmetry-related pyridine ring [H···Cg2 = 2.82, where Cg2 is the centroid of N1/C1—C5 ring]. The combination of the above interactions help stabilize the crystal structure.

Experimental top

15 ml me thanol solution of Ni(ClO4).6H2O (0.2503 g, 0.684 mmol) was added into a 10 ml me thanol solution containing 2-(dimethl)amine-1,10-phenanthroline (0.1531 g, 0.686 mmol), and the mixed solution was stirred for a few minutes. Then 10 ml me thanol solution of NaSCN (0.1112 g, 1.37 mmol) was added into the mixed solution above. The green single crystals were obtained after the solution had been allowed to stand at room temperature for two weeks.

Refinement top

H atom of hydroxyl was located in a difference Fourier map and refined as riding in its as found position with Uiso(H) = 1.5 Ueq(O). Other H atoms were placed in calculated positions (C—H = 0.96 Å for methyl group and C—H = 0.93 Å for other H atoms) and refined as riding with Uiso = 1.5 Ueq(C) for methyl H and Uiso = 1.2 Ueq(C) for other H atoms.

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.
