    • A method of preparing a crystalline material, herein designated as SSZ-74, comprising contacting under crystallization conditions (1) a source of silicon oxide, (2) a source of another metal oxide, (3) fluoride ions, and (4) a structure directing agent comprising a hexamethylene-1,6-bis-(N-methyl-N-pyrrolidinium)dication. A method of preparing a crystalline material having a defined X-ray powder diffraction pattern, by (1) forming a reaction mixture having one or more metal oxides, one being silicon oxide, and a hexamethylene-1,6-bis-(N-methyl-N-pyrrolidinium)dication, (2) maintaining the reaction mixture at an elevated temperature until crystals are formed, (3) separating the crystalline material, and (4) optionally calcining the crystalline material. A method for preparing a crystalline material, comprising (1) forming a defined reaction mixture, (2) maintaining the reaction mixture under conditions where crystals are formed, (3) separating out the crystalline material, and (4) water-washing and drying the crystalline material such that it has a defined X-ray powder diffraction pattern.
