Kurzbeschreibung (Abstract)
Melonates, M-3/x(x)[C6N7(NCN)(3)], contain the aromatic and planar tricyanamino-s-heptazine anion. Only one example, the potassium derivative, has been isolated in pure form so far, but it has never been characterised comprehensively. Potassium melonate is obtained from a reaction of the polymer melon, [C6N9H3](n), with KSCN. C-13 NMR, FTIR, Raman, UV-vis and luminescence spectroscopy support the proposed molecular structure. The crystal structure of the hydrate K-3[C6N7(NCN)(3)]center dot 5H(2)O was determined by single crystal X-ray analysis (MoK alpha: Pbca (no. 161), a = 6.538(2), b = 24.033(6), c = 23.684( 6) angstrom and Z = 8). Thermogravimetric analysis shows that the dehydrated salt starts to decompose at temperatures above 500 degrees C. The [C6N7(NCN)(3)] unit is an ideal molecular building block for carbon(IV) nitrides, especially s-heptazine based graphite-like C3N4 networks.
