Varying the templating alkylammonium counterion results in different framework structures: [HNMe3][CuZn5Cl12] adopts the known sodalite structure, whereas [H2NEt2][CuZn5Cl12] exhibits a novel three-dimensional channel structure with eleven- and eight-ring channels (the latter is depicted on the right). Controlled addition of methanol or water results in formation of colloidal particles that are implicated as intermediates in the construction of open frameworks. References 1 W. M. Meier, D. H.

Mag. 1972, 38, 593. 12 Crystal data for CZX-1: C3H10CI12CuNZn5, Mr = 876.0 g mol−1, cubic, I43m (no. 217), a = 10.5887(3) Å, V = 1187.21(3) Å3, Z = 2, ρcalcd = 2.451 g cm−3, μ(MoKα) = 7.34mm−1, MoKα radiation (λ = 0.71073 Å). Data were collected at 293 K on a crystal with dimensions 0.25 × 0.20 × 0.14 mm. Final cell constrants were determined from a set of 24 reflections with 38<20<41°. Intensity data were collected over an octant with an Enraf-Nonius CAD4 diffractometer by the 0-20 scan method on hte limit of 0<30°. Of 986 reflections collected, 201 were unique. An absorption correction was made from empirical psi-scan data. The X-ray powder pattern indicated a sodalite structure, which was used as a starting model for the structure solution. The final refinement of 14 parameters was carried out by a full-matrix least-squares method on 191 independent reflections [I>1.0σ(I)]. All non-hydrogen atoms were refined anisotropically. The structure refined to R = 0.0194 and Rw = 0.0232. The maximum and minimum residual electron density was 0.28 and −0.43 e Å−3. 13(a) W. Schnick, J. Lüke, Angew. Chem. 1992, 104, 208; Angew. Chem.

Data were collected at 293 K on a crystal with dimensions 0.32 × 0.20 × 0.10 mm crystal. Final cell constants were determined from a set of 24 reflections with 40<2θ<46°. An Enraf-Nonius CAD4 diffractometer data was used to collect intensity data for 3962 reflections (1887 unique) over a hemisphere by the θ − 2θscan method out of θ<30°. An absorption correction was made from empirical psi-scan data. The structure was solved by SIR92 and conventional Fourier techniques. A full-matrix least-squares calculation on 1696 independent reflections [I>1.0σ(I)] was used in the final refinement of 44 parameters. The Cu, Zn, and CI atoms were refined anisotropically; H atoms were not included in the refinement. The structure refined to R = 0.0330 and Rw = 0.0516. The maximum and minimum residual electron density was 1.16 and −1.06e Å−3. 17 Crystal data for CZX-3: C2H8Cl12Cu2N2Zn4, Mr = 906.3 g mol−1, orthorhombic, I212121 (no. 24), a = 9.5677(16), b = 9.4554(12), c = 13.6435(16) Å, V = 1234.3(3) Å3, Z = 2, ρcalcd = 2.439 g cm−3, μ(MoKα) = 6.73 mm−1, MoKα radiation (λ = 0.71073 Å).

An Enraf-Nonius CAD4 diffractometer was used to collect intensity data for 1231 reflections (1095 unique) over an octant by the θ–2θ scan method out to θ<25°. The Structure was solved by using the CZX-2 structure as a model and conventional Fourier techniques. A fullmatrix least-squares calculation on 814 independent reflections [I>1.5σ(I)] was used in the final refinement of 58 parameters. All non-hydrogen atoms were refined anisotropically, R = 0.0418, Rw = 0.0343. The maximum and minimum residual electron density was 0.54 and −0.58 e Å−3.
