Compound I was synthesized by direct method in a molar ratio of 1:3:1 of Co(NO3)2·6H2O, 4,4'-bpy and KSCN, respectively. To prepare the reaction mixture, Co(NO3)2·6H2O (0.5 mmol, 0.15 g) and KSCN (0.5 mmol, 0.05 g) were dissolved in water (10 mL). Then 10 ml of ethanoic solution of 4,4'-bpy (1.5 mmol, 0.23 g) was added. The mixture was stirred, then 10 mL of DMSO and 0.5 mL of 6 M HNO3 was slowly added to assist dissolution.The mixture was then heated at 60 °C for 15 mins. It was set at room temperature for a slow evaporation. After 15 days, pink crystals were obtained.
C-bound H atoms were positioned geometrically, with C—H = 0.93 (aromatic) or 0.96 Å (methyl), and included as riding atoms, with Uiso(H) = 1.5Ueq (C) for methyl groups and 1.2Ueq(C) otherwise.
Metal organic frameworks can be prepared in variety methods and there are many effects influencing their structures. The solvent used in preparing is one of the most important effects on the structures. The influence of the solvent on the structure has been widely studied, for example in the study of iron(II) thiocyanato coordination polymers based on 4,4'-bipyridine using methanol as a solvent (Wriedt & Näther, 2010). This finding suggested that if more solvent and higher concentration of N-donor ligand were applied the structure is likely to involve with solvent coordination and the different metal to organic ligand ratio. The solvent has the influence on both metal to organic ligand ratio and the arrangement of the organic linker leading to the variation of the dimension and topology of the network (Yao & Wang, 2009). In addition, the type of N-donor organic linkers also affect the structure (Wriedt & Näther, 2009; Wriedt et al., 2009).
Of interest to us was this effect. A new structure with the different metal to N-donor organic ligand ratio might also be possible by alteration of the solvent, type of N-donor organic ligand, and the metal to N-donor ligand ratio in the preparation. In this contribution, we present synthesis and structural characterization of a two-dimensional framework of poly[µ-tris(4,4'-bipyridine)di(dimethyl sulfoxide)tetrathiocyanato-N-dicobalt(II)] (I)
The asymmetric unit of the title compound consists of one CoII centre, two SCN- anions, one and a half 4,4'-bpy molecules and one DMSO molecule (Fig. 1). The CoII is surrounded by two N atoms from terminal SCN- groups, one O atom from DMSO and three N atoms from three 4,4'-bpy (Table 1). The 4,4'-bpy acts as a bridge linking metal centres and generates a two-dimensional structure with rectangular spaces (11.60 x 23.25 Å) within layer (Fig. 2). Due to the arrangement of the linker and metal to N-donor organic ligand ratio of 1:1.5, the space within the layer is twice as compared to the related two-dimensional compound {[Fe(4,4'-bpy)2(SCN)2](MeOH)2}n (Wriedt & Näther, 2010). The layers are stacked in an ABC fashion (Fig. 3). The plane parallel to the layer is (103). The metal atoms in one layer sit above or below the rectangular spaces. As a result, the terminal SCN- and DMSO ligands arrange approximately perpendicular to the layer plane and fill up the spaces between adjacent layers. This arrangement of the layers is in the ABC fashion preventing the occurrence of the interlayer spaces along the crystallographic c axis and hence leading to the absence of lattice solvent and/or organic guest molecules in the interlayer spaces (Fig. 3). In addition, the extended structure of I has been illustrated (Fig. 4). The hydrogen bonds between H1 and S1 link the layers with the distance of 2.82 Å (Table 2). As a result, these layers are assembled into a three-dimensional supramolecular framework.

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. |

Metal organic frameworks can be prepared in variety methods and there are many effects influencing their structures. The solvent used in preparing is one of the most important effects on the structures. The influence of the solvent on the structure has been widely studied, for example in the study of iron(II) thiocyanato coordination polymers based on 4,4'-bipyridine using methanol as a solvent (Wriedt & Näther, 2010). This finding suggested that if more solvent and higher concentration of N-donor ligand were applied the structure is likely to involve with solvent coordination and the different metal to organic ligand ratio. The solvent has the influence on both metal to organic ligand ratio and the arrangement of the organic linker leading to the variation of the dimension and topology of the network (Yao & Wang, 2009). In addition, the type of N-donor organic linkers also affect the structure (Wriedt & Näther, 2009; Wriedt et al., 2009).
Of interest to us was this effect. A new structure with the different metal to N-donor organic ligand ratio might also be possible by alteration of the solvent, type of N-donor organic ligand, and the metal to N-donor ligand ratio in the preparation. In this contribution, we present synthesis and structural characterization of a two-dimensional framework of poly[µ-tris(4,4'-bipyridine)di(dimethyl sulfoxide)tetrathiocyanato-N-dicobalt(II)] (I)
The asymmetric unit of the title compound consists of one CoII centre, two SCN- anions, one and a half 4,4'-bpy molecules and one DMSO molecule (Fig. 1). The CoII is surrounded by two N atoms from terminal SCN- groups, one O atom from DMSO and three N atoms from three 4,4'-bpy (Table 1). The 4,4'-bpy acts as a bridge linking metal centres and generates a two-dimensional structure with rectangular spaces (11.60 x 23.25 Å) within layer (Fig. 2). Due to the arrangement of the linker and metal to N-donor organic ligand ratio of 1:1.5, the space within the layer is twice as compared to the related two-dimensional compound {[Fe(4,4'-bpy)2(SCN)2](MeOH)2}n (Wriedt & Näther, 2010). The layers are stacked in an ABC fashion (Fig. 3). The plane parallel to the layer is (103). The metal atoms in one layer sit above or below the rectangular spaces. As a result, the terminal SCN- and DMSO ligands arrange approximately perpendicular to the layer plane and fill up the spaces between adjacent layers. This arrangement of the layers is in the ABC fashion preventing the occurrence of the interlayer spaces along the crystallographic c axis and hence leading to the absence of lattice solvent and/or organic guest molecules in the interlayer spaces (Fig. 3). In addition, the extended structure of I has been illustrated (Fig. 4). The hydrogen bonds between H1 and S1 link the layers with the distance of 2.82 Å (Table 2). As a result, these layers are assembled into a three-dimensional supramolecular framework.
