Herein,　homogeneous　solutions　of　cationic　gemini　surfactants,　alkanediyl-alpha,omega-bis(dimethyldodecylammonium　bromide),　referred　to　as　12-s-12　where　s　=　2,　4,　6,　8,　and　10,　in　cyclohexane　have　been　prepared　with　the　help　of　sodium　hexanoate　(SH)　or　sodium　laurate　(SL).　These　surfactants　self-assembled　in　cyclohexane　to　form　various　aggregating　structures,　which　were　characterised　by　small-angle　X-ray　scattering　(SAXS)　together　with　polarised　microscopy　observations.　The　results　showed　that　12-2-12/SH,　where　the　gemini　had　the　shortest　spacer　among　this　series,　formed　an　inverse　micellar　cubic　liquid　crystalline　phase　of　the　Fd3m　structure.　12-s-12/SL,　including　s　=　4,　6,　and　8,　which　contained　an　adequate　length　spacer,　formed　an　inverse　hexagonal　liquid　crystalline　phase　packed　by　the　cylindrical　assemblies　of　surfactants.　12-10-12/SL,　in　which　the　gemini　had　a　longer　spacer,　formed　dispersed　reverse　vesicles　(a　lamellar　structure).　The　rheological　properties　of　liquid　crystalline　phases　in　a　linear　visco-elastic　regime　were　studied.　12-2-12/SH　formed　a　hard　gel,　whereas　12-s-12/SL　formed　soft　gels.　Dynamic　light　scattering　and　steady-state　viscosity　analyses　were　performed　for　the　reverse　vesicle　solutions　formed　by　12-10-12/SL.　In　all　these　systems,　the　amount　of　added　water　W-0,　denoting　the　mole　ratio　of　water　to　the　gemini　surfactant,　was　demonstrated　to　influence　the　properties.
