Abstract
The synthesis of crystalline Be(CN)2 and Mg(CN)2 has been demonstrated and X-ray diffraction studies indicate simple-cubic structures with four-coordinate metal atoms surrounded by an average of two N and two C atoms. The symmetry of Be(CN)2 is Pn3̄m, a = 5.339(1) Å, Z = 2. The symmetry of Mg(CN)2 is also Pn3̄m, a = 6.122(1) Å, Z = 2. A thallium cyanide with composition Tl(CN)2 was prepared and was shown to have a similar simple-cubic structure with a = 6.660(1) Å. On the basis of the X-ray diffraction pattern, IR spectra, and combustion analysis, this material is assigned the formula TlITlIII(CN)4. Crystalline Al(CN)3 with simple-cubic structure has been prepared for the first time. Rietveld refinement indicated that the structure incorporates CN groups with orientational disorder in a Prussian-blue-like octahedral network. 27Al NMR spectroscopy confirmed C,N disorder in cubic Al(CN)3. The symmetry for Al(CN)3 is Pm3̄m, a = 5.205(1) Å.
