Li6Na3Sr14Al11P22O90: an oxo-centered Al3 cluster based phosphate constructed from two types of (3,6)-connected kgd layers†
Abstract
A novel and thermally stable aluminum phosphate Li6Na3Sr14Al11P22O90 (1) has been achieved by using a solid-state molten method, which contains an oxo-centered trinuclear cluster and an anti-Lowenstein's rule Al–O–Al linkage and is constructed from two types of (3,6)-connected kgd layers [Al(Al3O)(PO4)7]25− and [Al(PO4)2]3−. The good optical transparency in the whole UV range and excellent thermal stability make the title compound a potential optical window material.
