New calcium germanium nitrides: Ca2GeN2, Ca4GeN4, and Ca5Ge2N6.

New calcium germanium nitrides: Ca2GeN2, Ca4GeN4, and Ca5Ge2N6.

We report three new calcium germanium nitrides synthesized as crystals from the elements in sealed niobium tubes at 760 degrees C using liquid sodium as a growth medium. Black Ca2GeN2 is isostructural with the previously reported strontium analogue. It is tetragonal P4(2)/mbc (no. 135) with a = 11.2...
