Abstract

Abstract Miscellaneous tetrasubstituted ammonium salts of [Pt 3 n (CO) 6 n ] 2– ( n = 5–8) clusters, obtained by the stoichiometric oxidation of the corresponding [Pt 9 (CO) 18 ] 2– salts with tropylium tetrafluoroborate, self‐assemble into infinite semicontinuous or continuous {[Pt 3 n (CO) 3 n (μ‐CO) 3 n ] 2– } ∞ conductor wires upon crystallization. Pellets of these salts exhibit conductor behavior that roughly depends on the interdianion gap along the wires. (© Wiley‐VCH Verlag GmbH &amp; Co. KGaA, 69451 Weinheim, Germany, 2007)
