title: Lithium zincopyrophosphate, Li(2)Zn(3)(P(2)O(7))(2).
abstract: The title compound, dilithium(I) trizinc(II) bis[diphosphate(4-)], is the first quaternary lithium zincopyrophosphate in the Li-Zn-P-O system. It features zigzag chains running along c, which are built up from edge-sharing [ZnO(5)] trigonal bipyramids. One of the two independent Zn sites is fully occupied, whereas the other is statistically disordered by Zn(2+) and Li(+) cations, although the two Zn sites have similar coordination environments. Li(+) cations occupy a four-coordinated independent site with an occupancy factor of 0.5, as well as being disordered on the partially occupied five-coordinated Zn site with a Zn(2+)/Li(+) ratio of 1:1.
