Bis(μ-1,2-bis­{[2-(2-pyrid­yl)-1H-imidazol-1-yl]meth­yl}benzene)bis­[bis­(thio­cyanato-κN)cadmium(II)]

The asymmetric unit of the binuclear title compound, [Cd₂(NCS)₄(C₂₄H₂₀N₆)₂], contains one half-mol­ecule, consisting of one Cd²⁺ cation, two half 1,2-bis­{[2-(2-pyrid­yl)-1H-imidazol-1-yl]meth­yl}benzene (L) ligands and two SCN⁻ anions. The dimeric cyclic mol­ecule is completed by crystallographic inversion symmetry. The Cd²⁺ cation is coordinated by two N atoms from two SCN⁻ anions and four N atoms from two symmetry-related L ligands, exhibiting a distorted octrahedral coordination. A two-dimensional supra­molecular network stacked parallel to [210] is finally formed by linking these dimers through weak π–π stacking inter­actions between the pyridine rings and benzene rings of adjacent dimers, with a plane-to-plane distance of 3.36 (6) Å and a centroid–centroid distance of 3.67 (2) Å. One of the thio­cyanate S atoms is equally disordered over two positions.

S1. Comment

Interest in cadmium compounds was provoked by their luminescent properties (Yam & Lo, 1999; Zheng et al., 2004). A number of cadmium compounds have been reported with different N-donor ligands. In this paper, we present the hydrothermal synthesis and crystal structure of the title compound, (I), [Cd₂(C₂₄H₂₀N₆)₂(SCN)₄], based on the 1,2-bis{[2-(2-pyridyl)-1H-imidazol-1-yl]methyl}benzene ligand (hereafter L).

The asymmetric unit of (I) contains one Cd²⁺ cation, two halfs of the L ligand and two SCN^- anions. Two complete L ligands link two Cd²⁺ cations to form a centrosymmetric dimeric ring. So the asymmetric unit contains only half of the ring molecule (Fig. 1). The Cd²⁺ cation is coordinated to the N atom of two SCN^- anions and four N atoms from symmetry-related L ligands within normal Cd—N distances (Dai et al., 2002; Luan et al., 2006; Wang et al., 2003). The resulting CdN₆ polyhedron can be considered as a distorted octahedron. Each dimer links adjacent dimers via π–π interactions between pyridine rings and benzene rings to form a 2D supramolecular network stacked along [210] (Fig. 2), with a plane to plane distance of 3.36 (6) Å and a centroid-centroid distance of 3.67 (2) Å.

S2. Experimental

A mixture of Cd(OAc)₂^.2H₂O (0.13 g, 0.50 mmol), L (0.2 g, 0.5 mmol), KSCN (0.10 g, 1 mmol) and H₂O (10 ml) was stirred for 1 h, and then transferred and sealed in a 25 ml Teflon-lined stainless steel container. The container was heated to 423 K, held at that temperature for 72 h, and cooled to room temperature at a rate of 10 Kh^-1. Colourless parallelepipeds of (I) were collected in 78% yield.

S3. Refinement

One of the SCN^- groups is disordered over two positions. The S atom was refined with a 0.5:0.5 occupancy ratio. All H atoms on C atoms were positioned geometrically and refined as riding atoms, with C—H = 0.93 Å for aromatic C atoms, and with C—H = 0.97 Å for aliphatic C atoms, and U_iso=1.2 or 1.5U_eq(C).

Special details

Geometry. All esds (except the esd in the dihedral angle between two l.s. planes) are estimated using the full covariance matrix. The cell esds are taken into account individually in the estimation of esds in distances, angles and torsion angles; correlations between esds in cell parameters are only used when they are defined by crystal symmetry. An approximate (isotropic) treatment of cell esds is used for estimating esds 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 > 2sigma(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.
