Radical Ion 1 Hexafluorophosphate

For details of the electrolysis, see Section B. The solutions needed for the cell consist of 0.581 g (1.5 mmol) of [CH3(CH2)3]4N[PF6] in 10 mL of dry TCE and 0.027 g (0.06 mmol) of TMTSF in 5 mL of dry TCE. After electrolysis for 3-5 days at 5 xA, the crystals are harvested when the TMTSF solution begins to lose its pink color. This procedure yields 25 mg (80.0%) of metallic black crystals of bis(4,4, 5,5 -tetramethyl-2,2 -bi-l,3-diselenolylidene) hexafluorophosphate, (TMTSF)2[PFJ. 

All of the synthetic metals discussed herein are isostnictural and triclinic (space group PI). The identifying crystal lattice parameters are given in Table I. 

The unusual electrical properties of the 2 1 TMTSF salts are summarized and discussed elsewhere. For additional characterization purposes beyond chemical analyses, the crystallographic lattice constants for the isostructural (triclinic, space group PT) TMTSF derivatives discussed here are given in Table I.
