Claim:
A layered crystalline composition having an empirical composition in the as-synthesized form and on an anhydrous basis expressed by an empirical formula of: M m n+ R r p+ Al 1-x E x Si y O z where M is at least one exchangeable cation selected from the group consisting of alkali metal ions, alkaline earth metal ions, and rare earth metal ions, “m” is the mole ratio of M to (Al+E) and varies from about 0.05 to about 10.0, R is an organoammonium cation or amine selected from the group of hexyltrimethylammonium (HTMA + ), hexamethonium, pentyltrimethylammonium, choline, ethyltrimethylammonium (ETMA + ), diethyldimethyl ammonium (DEDMA + ), trimethylpropylammonium, trimethylbutylammonium, dimethyldiethanolammonium, tetraethyl ammonium (TEA + ), tetrapropylammonium (TPA + ), dimethylhexylamine, diethanolamine, and mixtures thereof, “r” is the mole ratio of R to (Al+E) and has a value of about 0.5 to about 10.0, “n” is the weighted average valence of M and has a value of about 1 to about 3, “p” is the weighted average valence of R and has a value of about 1 to about 2, E is an element selected from the group consisting of gallium, iron, boron and mixtures thereof, “x” is the mole fraction of E and has a value from 0 to about 1.0, “y” is the mole ratio of Si to (Al+E) and varies from greater than 5 to about 40 and “z” is the mole ratio of O to (Al+E) and has a value determined by the equation: z =( m·n+p·r+ 3+4· y )/2 and is characterized in that it has the x-ray diffraction pattern having at least the d-spacings and intensities set forth in Table A: TABLE A 2θ d (Å) I/Io % 5.32-5.88 16.60-15.02 m-vs 8.10-8.94 10.91-9.89 w-m 12.40-12.75 7.13-6.94 w-m 13.15-13.65 6.73-6.48 m 21.10-21.55 4.21-4.12 m 22.00-22.40 4.04-3.97 m 23.55-23.88 3.78-3.72 w-m 24.95-25.31 3.57-3.52 m-vs 25.47-25.88 3.49-3.44 m 28.06-28.44 3.18-3.14 w-m 49.78-50.28 1.83-1.81 m.
