(Received 3 August 2010; accepted 8 August 2010; online 18 August 2010)

The title three-dimensional coordination network, {[Dy(C₄H₄N₂O₂)₄](ClO₄)₃}_n, is isostructural of other lanthanides. The Dy⁺³cation lies on a fourfold roto-inversion axis. It is coordinated in a distorted square-antiprismatic fashion by eight O atoms from bridging pyrazine N,N′-dioxide ligands. There are two unique pyrazine N,N′-dioxide ligands. One ring is located around an inversion center, and there is a a twofold rotation axis at the center of the other ring. There are also two unique perchlorate anions. One is centered on a twofold rotation axis and the other on a fourfold roto-inversion axis. The perchlorate anions are located in channels that run perpendicular to (001) and (110) and interact with the coordination network through C—H⋯O hydrogen bonds.

Comment top

The description of the structure of the title compound is part of a series of consecutive papers on three-dimensional coordination networks of the type {[Ln(C₄H₄N₂O₂)₄](ClO₄)₃}_n, with Ln = Nd (Quinn-Elmore et al. 2010), Dy (this publication), Ho (Buchner et al. 2010a) and Er (Buchner et al. 2010b), respectively. All four compounds are also isostructural to the previously reported La, Ce, Pr, Sm, Eu, Gd, Tb and Y coordination networks (Sun et al. 2004). The background to this study is given in ther first article of this series by Quinn-Elmore et al. (2010).

Experimental top

Pyrazine N,N'-dioxide (0.025 g, 0.223 mmol) was dissolved in deionized water (1.5 ml) and methanol (1.5 ml). An aqueous solution of Dy(ClO₄)₃ (0.320 ml of a 0.0868 M solution, 0.028 mmol) was diluted with methanol (0.680 ml) and CH₂Cl₂ (2.5 ml). The pyrazine N,N'-dioxide solution was layered over the Dy(ClO₄)₃ solution, and the two solutions were allowed to slowly mix. Colorless block-like crystals formed upon the slow evaporation of the resultant solution.

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.
