- W2063505890 abstract "Abstract The crystal structure of zeolite 4-A solvated with methanol, stoichiometry Na12Si12Al12O48·9CH3OH per unit cell, has been studied by single crystal X-ray diffraction techniques in the cubic space group Pm3m; a = 12.298(2) A . The 12 Na+ cations occupy three sites: six at Na(1) are on threefold axes near the centres of 6-rings, three at Na(2) are associated with 8-ring oxygens and three at Na(3) are in the large cavity opposite 4-rings. The nine methanol oxygens, all in the large cavity, associate with the 12 Na+ ions in two ways: six oxygens bridge between 6-ring and 4-ring Na+ ions, and three coordinate to 8-ring Na+ ions. As compared to hydrated or dehydrated zeolite 4-A, two Na+ ions have moved from 6-ring to 4-ring sites R1 = 0.062 for 381 reflections. In the acetonitrile sorption complex of zeolite 4-A, the occupancies of the Na(1), Na(2) and Na(3) ions are again found to be six, three and three, respectively. The Na(2) and Na(3) positions are, however, more like those in dehydrated zeolite 4-A. Two positions, X(1) and X(2), which inaccurately represent acetonitrile density, have been found. Two X(1)'s bridge from each Na(3) ion to two Na(1) ions as in Na12-A · 9CH3OH. Unlike that structure, two X(2)'s are found to be coordinated to each Na(2) ion, R1 = 0.083 for 375 reflections." @default.
