Selenium substitution of the outer 1,3-dithiole rings of TTM-TTP and TMET-TTP has been performed. The selenium analogues of TTM-TTP give the phases isostractural to (TTM-TTP)(I3)5/3. The selenium substitution of the single outer ring does not suppress the 25 K transition, whereas the substitution of both outer rings affords a practically metallic phase.
