Abstract top

The title compound, [Ni(SO4)(C5H5N)(H2O)3]n, was synthesized by the hydrothermal reaction of NiSO4·6H2O, pyridine and water. The central NiII atom is coordinated in a distorted octahedral environment by a pyridine N atom, three aqua O atoms and two O atoms of bridging sulfate anions, yielding a zigzag chain. A three-dimensional network is generated via complex hydrogen bonds involving the sulfate and aqua ligands and a pyridine C-H group.

Comment top

The asymmetric unit contains one independent Ni atom, which is octahedrally coordinated by two sulfato anions, three aqua ligands and one pyridine molecule. The bond lengths and angles involving Ni—O(aqua), Ni—N are similar to those of other nickel-carboxylate coordination polymers with pyridine (Wang et al., 2006; Stein et al., 2007), with the Ni center displaying the typical distorted octahedral coordination, which can be viewed from the angles of N1—Ni1—O1 177.81 (10)°, N1—Ni1—O7 91.13 (11)°, O1—Ni1—O6 92.13 (9)°, O5—Ni1—O6 92.91 (10)° (Fig. 1). The SO42- dianion acts as a µ2 bridging ligand, linking two adjacent metal ions and generating a one-dimensional zigzag chain (Fig. 2). The aqua ligands, sulfato groups and C—H of pyridine form extensive hydrogen-bonding interactions (Table 1), resulting in a three-dimensional network (Fig. 3).

Experimental top

Samples of NiSO4.6H2O (0.1 mmol) and pyridine (0.1 mmol) were placed in a thick-walled Pyrex tube (ca 20 cm long). After addition of H2O (1 ml), the tube was frozen with liquid nitrogen, evacuated under vacuum and sealed with a torch. The tube was heated at 110°C for 2 days and then was slowly cooled down to room temperature, and light-green block-shaped crystals were obtained. Yield: 35%.

Refinement top

The H atoms bonded to C atoms were positioned geometrically and refined using a riding model with Uiso(H) = 1.2Ueq(C) (C—H = 0.95 Å). Water H positions were located in an electron-density difference map and refined freely.

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.
