The synthesis and characterisation of JBW-type zeolites. Part B: Sodium/rubidium aluminogermanate, Na2Rb Al3Ge3O12 center dot H2O
An aluminogermanate possessing the zeolite JBW framework topology has been synthesized from a sodium- and rubidium-containing reagent mixture. The material, of composition Na2RbAl3Ge3O12. H2O, has been structurally characterized via single crystal X-ray diffraction, and adopts space group Pmn2(1) with cell parameters a=15.6241(9), b=8.2586(6), and c=5.2442(6) Angstrom. The material possesses a strictly alternating array of framework AlO4 and GeO4 tetrahedra, displaying no evidence of the superlattice observed for the aluminosilicate analogue. Sodium cations reside in the dehydrated six-rings, with rubidium cations and water molecules in the eight-rings. The structural parameters are compared with those derived for other materials possessing JBW topology.

Abstract
An aluminogermanate possessing the zeolite JBW framework topology has been synthesized from a sodium- and rubidium-containing reagent mixture. The material, of composition Na2RbAl3Ge3O12. H2O, has been structurally characterized via single crystal X-ray diffraction, and adopts space group Pmn2(1) with cell parameters a=15.6241(9), b=8.2586(6), and c=5.2442(6) Angstrom. The material possesses a strictly alternating array of framework AlO4 and GeO4 tetrahedra, displaying no evidence of the superlattice observed for the aluminosilicate analogue. Sodium cations reside in the dehydrated six-rings, with rubidium cations and water molecules in the eight-rings. The structural parameters are compared with those derived for other materials possessing JBW topology.
