was selected for the crystal structure measurement. The X-ray diffraction intensity was recorded by a Bruker Smart-1000 CCD diffractometer with graphite monochromatized Mo Ka radiation (k = 0.071073 nm). Crystal data and conditions of the intensity measurements are given in Table 1. The main bond lengths and angles for Li(C2N2H10)[In2(HPO4)3(PO4)] is listed in Table 2. CCDC 773388 contains the supplementary crystallographic data for this paper.
