Pyrophosphates and pyrovanadates

I pirofosfati (P2O4)−7 sono presenti in alcuni minerali naturali. La formula generale può essere rappresentata da A2M(H2P2O7)2•2H2O. Generalmente cristallizzano sia nel gruppo spaziale triclino che in quello ortorombico. La molecola H2P2O7è l'unità dominante, mentre A = (K, Rb, NH4, Tl), M = (Zn, Cu...
