New one-dimensional tetracyanoplatinate (TCP) conductors of the type M/sub 2/(Pt(CN)/sub 4/)(FHF)/sub 0//sub .//sub 39//sub en-dash//sub 0//sub .//sub 40/ where M=Rb/sup +/, Cs/sup +/, and K/sub 2/(Pt(CN)/sub 4/)(FHF)/sub 0//sub .//sub 30/xxH/sub 2/O, were studied by infrared techniques and the fluorine in these compounds was shown to be present as the bifluoride ion (FHF)/sup -/. The asymmetric hydrogen--fluorine stretching vibration was found to be cation dependent, and occurs at higher frequency for the K/sup +/ salts, as compared to the Rb/sup +/ and Cs/sup +/ salts. In contrast to the anion and cation-deficient one-dimensional TCP conductors, only one intense CN stretching mode at approx.2150 cm/sup -1/ was observed. The rubidium and cesium salts are lustrous, metallic-gold in color, and appear to be optically different from the reddish-bronze prototype materials, K/sub 2/(Pt(CN)/sub 4/)X/sub 0//sub .//sub 3/ x3H/sub 2/O where X=Br or Cl.
