In the title compound, {[Co(NCS)2(C16H20N6O)2]·2C3H7NO·2H2O}n, each CoII ion located on an inversion center is six-coordinated by four equatorial N atoms from four different 4-tert-butyl-2,6-bis­(1,2,4-triazol-1-ylmeth­yl)phenol (L) ligands, and by two N atoms from two axial thio­cyanate anions [Co—N = 2.104 (3)–2.144 (3) Å]. The metal centres are connected via the bidentate L ligands into two-dimensional polymeric layers parallel to bc plane. The dimethyl­formamide and solvent water mol­ecules participate in inter­molecular O—H⋯O and O—H⋯S hydrogen bonds, which consolidate the crystal packing.

Comment top

Ligand 2,6-bis(1,2,4-triazol-1-ylmethyl)-4-tert-butyl-phenol (bttp) has been used to generate various metal-organic architectures with different transitional metal ions due to its polydentate character and bridging ability (Chu et al., 2007, 2008; Ma et al., 2003; Zhu et al., 2004, 2007). As a further study of such complexes, the title CoII complex is reported in this paper.

Each CoII atom exhibits a slightly distorted octahedral environment with four nitrogen atoms from the triazole groups of four bttp ligands in the equatorial plane, and two nitrogen atoms from two thiocyanate ligands at the axial positions (Fig. 1). Each ligand adopts a cis conformation in which two triazole groups are on the same direction of the central phenyl ring. The dihedral angles between the phenyl ring and the two triazole rings are 97.8 (3) ° and 88.8 (3) °, respectively. The two triazole rings are inclined to one another, with a dihedral angle of 65.3 (3) °. Each bttp serves as a bidentate bridging ligand via two exodentate nitrogen atoms at the 4-position of the triazole rings while the nitrogen atoms at 1,2-positions remain uncoordinated. In this way four metal atoms and four bttp ligands form a 48-membered [M4L4] metallocyclic ring, which is further assembled into a two-dimensional network via Co–N coordination bonds (Fig. 2). The Co···Co distance linked by the bridged bttp ligand is 11.604 (1) Å. The water oxygen atom is uncoordinated, and contributes to the formation of O–H···O and O–H···S hydrogen-bonding interactions with phenol group and DMF molecule (Table 1).

Experimental top

All solvents and chemicals were of analytical grade and were used without further purification. Ligand bttp was prepared via a one-step Mannich reaction as a white powder in 57% yield (Yan et al., 1994). For the synthesis of title compoud, a solution of bttp (0.1 mmol), Co(NO3)2.6H2O (0.1 mmol) and NH4SCN (0.25 mmol) in 30 ml e thanol was refluxed for 2 h, and then cooled to room temperature and filtered. The collected solid was dissolved in 1 ml DMF, and 20 ml e thanol was added to this solution. The mixture was left to stand at room temperature for two weeks and pink crystalline products were obtained (30.5 mg, 62%). Anal. Calcd. for C40H58CoN16O6S2: C, 48.92; H, 5.95; N, 22.82. Found: C, 48.88; H, 5.98; N, 22.72.

Refinement top

All H atoms were geometrically positioned (C–H 0.93–0.97 Å, O–H 0.82–0.85 Å), and refined as riding, with Uiso(H)=1.2-1.5 Ueq of the parent atom.

Experimental. The structure was solved by direct methods (Bruker, 2000) and successive difference Fourier syntheses.

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.
