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 consisting of trimethylbutylammonium, diquat-4, pentyltrimethylammonium, choline, ethyltrimethylammonium (ETMA + ), diethyldimethyl ammonium (DEDMA + ), trimethylpropylammonium, 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 10 to about 35 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/I 0 % peaks 3.98-4.14 22.18-21.33 m-vs 7.90-8.68 11.18-10.18 m-vs 10.55-10.84 8.38-8.16 w-m 12.72-13.16 6.95-6.72 m 17.00-17.12 5.21-5.18 m 20.70-21.50 4.29-4.13 m br 24.44-24.61 3.64-3.61 m-s sh 25.57-26.00 3.48-3.42 vs br 28.84-29.45 3.09-3.03 w-m br 49.92-50.19 1.83-1.82 m-s.
