Ca(11)N(6)(CN(2))(2) and Ca(4)N(2)(CN(2)): The True Nature of an "Unusual Binary Nitride" Is Finally Revealed.
One calcium nitride less! Several different binary nitrides of calcium have been reported: Ca(3)N(2), Ca(2)N, Ca(3)N(4), and Ca(11)N(8). X-ray structural analysis and spectroscopy revealed the latter is actually calcium nitride cyanamide and one of, so far, two examples of a new class of ternary phases (see boxes in the phase diagram).
