(LnM–Cm–)x: Hypothetical organometallic polymers with metallapolyyne and metallacumulene character*

Abstract

A class of (–L_nM–C_m–)_x hypothetical polymers, m = 2–4, conceptually derived from experimentally known analogous rigid-rod organometallic polymers and with different electron counts, obtained by varying the metal and the ligands in the ML_n fragment, have been studied using extended-Hückel tight-binding calculations. The results suggest interesting conducting properties, depending on the electron count and the length of the bridging C_m chain.
