| Abstract: | A Novel Periodate: On the Structure of K9Li3I2O13 = K9Li3OIO6]2 New obtained are weakly dichroitic (pale yellow/bluish) single crystals of K9Li3I2O13 by reaction of KIO4, K2O, and Li2O (KIO4:K2O:Li2O = 1:1:1.5; 800°C, 42 d). Space group P62c, Z = 2, a = 954.9 pm, c = 1172.2 pm, R = 6.2%, Rw = 5.6%, 957 symmetry independend I0(hkl), MoKα . Characteristic for this structure are ?isolated”? O2? and octahedral groups IO6]. The crystal structure has been determind. The Madelung Part of Lattice Energy, MAPLE, is calculated and discussed. |
