Synthesis and Structure Solution of Zeolite SSZ-65
This report describes the synthesis and structure solution of the new zeolite SSZ-65. SSZ-65 may be prepared as either a borosilicate (Si52.5B1.5O108) or an aluminosilicate using 1-[1-(4-chloro-phenyl)-cyclopropylmethyl]-1-ethyl-pyrrolidinium as a structure-directing agent. The structure of SSZ-65 was determined with the FOCUS Fourier recycling method. The framework of SSZ-65 possesses a two-dimensional system of intersecting 12-ring channels with pore apertures of 6.9 Angstroms x 5.9 Angstroms . The topological symmetry of SSZ-65 is P6/mmm, but improvements in the Rietveld refinement of the powder diffraction data are obtained in space group P6/m (a = 16.8009(2) Angstroms and c = 12.6154(1) Angstroms ). The agreement values improve from Rwp = 0.116, Rp = 0.094, and R(F2) = 0.142 in P6/mmm to Rwp = 0.103, Rp = 0.085, and R(F2) = 0.092 in P6/m.
