“…The resonance Raman spectrum (Table IV) exhibited strong bands at 1298 and 1418 cm"1, which indicates that 5 contains both TTF3"• and TTF23". Recrystallization of 5 from acetonitrile, without special precautions to exclude oxygen or moisture, produced very thin needlelike crystals of (TTF)2CuC14 (6). The strong Raman band at 1414 cm"1 shows that this is a chlorocuprate(II) salt of the TTF cation radical.…”

Oxidation of tetrathiafulvalene (TTF) with Cu(BF4)2 in acetonitrile yielded (TTF)(BF4)2, a salt of the TTF dication. In acetonitrile, (TTF)CuCl4 was formed from CuCl2-2H20. In ethanol, (TTF)3(CuCl2)5 was obtained; it was converted, by recrystallization from acetonitrile, to (TTF)2CuCl4. From CuBr2 and TTF in acetonitrile, (TTF)CuBr3 was obtained, but in ethanol (TTF)3(CuBr2)5 was produced. Oxidation of TTF with HAuCi4-3H20 in acetonitrile or ethanol yielded (TTF)AuCl2 and (TTF)(AuCl4)2, respectively. These new metallotetrathiaethylenes were characterized by electronic, vibrational, EPR, and X-ray photoelectron spectroscopy and by measurement of the magnetic susceptibilities and electrical conductivity. Resonance Raman spectroscopy (RRS) proved especially valuable. The v} mode, involving primarily stretching of the central C=C bond in TTF, shifts from 1512 cm"1 11in TTF0 to 1416 and 1308 cm"1 in TTF+• and TTF2+, respectively. These large shifts are useful in assigning the oxidation state(s) of the TTF moiety in metallotetrathiaethylenes. For example, bands at 1418 and 1298 cm"1 in (TTF)3(CuCl2)5 indicate that is is a mixed-valence material formulated as (TTF+-)(TTF2+)2(CuC12")5.

“…The other two chloro ligands in the (HgCl3")" polymer act as bridging ligands with very asymmetric Hg-Cl bond lengths. The chloro ligand 0(12) has a strong equatorial bond at 2.395 (5) A and a substantially weaker axial interaction at 3.112 (5) A (Figure 2B). A similar situation obtains for the chloro ligand 0(11), which forms a somewhat less asymmetric bridging system with a Hg-Cl equatorial bond length at 2.545 (5) A and an axial Hg-Cl interaction at 2.982 (5) A.…”
