A composition comprising:

• (a) a source of a silicon oxide, and optionally a source of germanium oxide, or combination thereof;
• (b) a source of aluminum oxide, and optionally a source of boron oxide, gallium oxide, hafnium oxide, iron oxide, tin oxide, titanium oxide, indium oxide, vanadium oxide, zirconium oxide, or combination or mixture thereof;
• (c) a mineralizing agent (preferably hydroxide);
• (d) an organic structure directing agent (OSDA) comprising at least one isomer of the quaternary piperidinium cation of Formula (I):
• and
• (e) a compositionally consistent crystalline microporous solid of GME topology;
• wherein
• RA and RB are independently a C1-3 alkyl, or together with the N to which they are bound form a 5 or 6 membered saturated or unsaturated ring;
• and
• R2 R3, R5, and R6 are independently C1-3 alkyl;
• and wherein the quaternary piperidinium cation has an associated bromide, chloride, fluoride, iodide, or hydroxide anion.

A crystalline microporous solid of GME topology having pores at least some of which are occluded with at least one isomer of the quaternary piperidinium cation of Formula (I):

• wherein
• RA and RB are independently a C1-3 alkyl, or together with the N to which they are bound form a 5 or 6 membered saturated or unsaturated ring;
• and
• R2, R3, R4, R5, and R6 are independently H or C1-3 alkyl, provided at least two of R2, R3, R4, R5, and R6 are independently C1-3 alkyl;
• and wherein
• the quaternary piperidinium cation has an associated bromide, chloride, fluoride, iodide, nitrate, or hydroxide anion.
