The alkaline-earth metal cyanamides MgCN2, SrCN2, and BaCN2 were prepared by the reaction of melamine with the metal nitrides (Mg3N2, Sr2N, Ba3N2) at temperatures between 740 °C and 850 °C. MgCN2 was structurally characterized by X-ray analysis using powder methods (R3m, Z = 3, a = 327.34(1) pm, c = 1412.82(5) pm). The crystal structures of SrCN2 and BaCN2 were determined from X-ray single crystal data (SrCN2: Pnma, Z = 4, a = 1241.0(2) pm, b = 396.3(2) pm, c = 538.9(2) pm, BaCN2: R3c, Z = 18, a = 1528.2(2) pm, c = 701.3(2) pm). All compounds consist of the respective cations and CN22--anions with an increasing degree of distortion of the coordination polyhedra with increasing radii of the cations. The structural features are correlated with vibrational spectroscopic data.

Various metals, such as Ca, Mg, Al, Ti, Cr, Y, Zr, and Ta were anodically dissolved in an organic electrolyte composed of propylamine, acetonitrile, and tetrabutylammonium bromide. The electrode reactions were completely irreversible. At the cathode, the
