(K4Li4)Al8Ge8O32 8H(2)O, an Li+-exchanged potassium alumino-germanate with the zeolite gismondine (GIS) topology
(2003) In Acta Crystallographica. Section C: Crystal Structure Communications 59(8). p.74-76- Abstract
- The title compound, lithium potassium dialuminium diger-manium octaoxide dihydrate, (K,Li)-(Al,Ge)-GIS (GIS is gismondine), is the result of a 50% Li+ exchange into the K-(Al,Ge)- GIS structure. The (K,Li)-(Al,Ge)-GIS structure was determined from a 4 x 4 x 2 m m octahedral single crystal at the ESRF synchrotron X-ray source. The ion exchange results in a symmetry transformation from I2/a for K-(Al,Ge)-GIS to C2/c for (K,Li)-(Al,Ge)-GIS. The structural change is due to disordering of K+ ions with Li+ ions along the [001] channel and ordering of water molecules in the [101] channels. The distance between sites partially occupied by K+ ions increases from 2.19 (3) Angstrom in K-(Al,Ge)-GIS to 2.94 (3) Angstrom in (K,Li)-(Al, Ge)-GIS. The Li+... (More)

The Li+ ions occupy positions along the twofold axis at the intersection of the eight-membered-ring channels in a twofold coordination with water molecules. For the four closest framework O2- anions, the Li ... O distances are 3.87 (4) Angstrom. (Less)
