Zusammenfassung: | A single crystal of excessively Pb super(2+)-exchanged zeolite Y (|Pb sub(15.5) super(2+)(Pb sub(4)O sub(4)(Pb sub(16/19) super(2+)Pb sub(3/19) super(4+)) sub(4)) sub(4 .75)|[Si sub(117)Al sub(75 )O sub(384)]-FAU) was prepared by exchange of Na-Y (|Na sub(75)|[Si sub(117)A l sub(75)O sub(384)]-FAU, Si/Al = 1.56) with an aqueous stream 0.05 M Pb(C sub(2)H sub(3)O sub(2)) sub(2) at 294 K, followed by vacuum dehydration at 1 10 super(-6) Torr and 693 K. Its structure was determined at 100 K, by X-ray diffraction techniques in the cubic space group. |
