The title three-dimensional coordination network, {[Dy(C4H4N2O2)4](ClO4)3}n, is isostructural of other lanthanides. The Dy+3 cation 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.

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.

Refinement top

All H atoms were positioned geometrically and refined using a riding model with C—H = 0.95Å and with Uiso(H) = 1.2 times Ueq(C).

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.
