Abstract
An extended network, {[Dy4(OH)4(asp)3(H2O)8](ClO4)2⋅10 H2O}n, having three-dimensional channels with a spacing of 11.78 Å (see picture) has been prepared by mixing Dy(ClO4)3 and L-aspartic acid in aqueous solution, and subsequently adjusting the pH values to about 6.5 using aqueous NaOH solution. This open-framework compound is representative for the assembly of discrete lanthanide cubanes into supercubanes.

The intensity data was collected at 294 K on a Rigaku RAXIS IIc imaging-plate diffractometer using MoKα radiation (λ=0.71073 Å) from a rotating-anode generator operating at 50 kV and 90 mA (2θmin=3°, 2θmax=55°, 34 oscillation frames in the range of 0–180°, exposure 8 min per frame). A self-consistent semiempirical absorption correction based on Fourier coefficient fitting was applied using ABSCOR. Compound 2: C12H54Cl2Dy4N3O42, Mr=1633.48, orthohombic, P212121, a=14.011(3), b=18.822(4), c=23.421(5) Å, V=6176(2) Å3, Z=4, ρcalcd=1.757 Mg m−3, μ=4.958 mm−1, F(000)=3124, GOF=1.013. The data were collected on a Nonius Kappa CCD with MoKα radiation (λ=0.71073 Å) at 293 K. The structure was solved by direct methods and refined by full-matrix least-squares based on F 2 using the SHELXL 97 program. R1=0.0497, wR2=0.1354, 483 parameters, 12942 reflections [I>2σ(I)].
