(Received 26 September 2012; accepted 1 October 2012; online 6 October 2012)

The asymmetric unit of the title compound [Mn(NCS)2(C9H13N)4] consists of one MnII cation located on a center of inversion, one thio­cyanato anion, one 3-tert-butyl­pyridine ligand and one 4-tert-butyl­pyridine ligand in general positions. The tert-butyl group of the 4-tert-butyl­pyridine ligand is disordered over two sets of sites in a 0.60:0.40 ratio. The MnII cation is coordinated by six N atoms of four tert-butyl­pyridine ligands and two N-bonded thio­cyanato anions within a slightly distorted octa­hedral coordination environment.

Comment top

The structure determination of the title compound was performed as part of a project on the synthesis of new coordination polymers based on transition metal thiocyanates and the investigations of their magnetic behaviour (Boeckmann et al., 2010; Boeckmann et al., 2011). Within this project we have reacted manganese(II)thiocyanate monohydrate with 4-tert-butylpyridine in water, which resulted in the formation of crystals of the title compound by accident. Apparently, the 4-tert-butylpyridine was contaminated with 3-tert-butylpyridine to a degree that allowed the formation of a few single crystals of the title compound. It was on the other hand not possible to obtain phase pure crystalline powder samples. In the crystal structure Mn atoms are surrounded by six N atoms of four tert-butylpyridine ligands and two N-bonded thiocyanato anions in mutual trans orientation in a slightly distorted octahedral geometry (Fig. 1). Mn···N distances range from 2.180 (3) Å to 2.337 (2) Å. It is also worth mentioning that so far no other compound containing 3-tert-butylpyridine has been reported in the CSD.

Experimental top

The title compound was obtained accidently during the reaction of 28.4 mg Mn(NCS)2 × H2O (0.15 mmol) with 44.4 µL 4-tert-butylpyridine (0.30 mmol), obtained from Sigma Aldrich, in 1.50 ml water at RT in a closed 3 mL snap cap vial. After three weeks colourless needles of the title compound were obtained.

Refinement top

H atoms were positioned with idealized geometry and were refined isotropically with Uiso(H) = 1.2 Ueq(C) (1.5 for methyl H atoms) of the parent atom using a riding model with C—H = 0.95 Å for aromatic and 0.98 Å for methyl hydrogen atoms. The tert-butyl group of the 4-tert-butylpyridine ligand is disordered and was refined using a split model with fixed site occupation factors of 0.60 and 0.40. Distances between the methyl groups in the two disordered moieties were restrained to be equal.

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.
