Abstract
Polymeric compounds, consisting of square planar metal complexes which are polymerised to linear chains via axial bonded bridging ligands, are new examples for one-dimensional conductors. The synthesis and crystal structure of polymeric bis-(dimethylglyoximato) and bis-(diphenylglyoximato) complexes of Fe(II) and Co(II) with pyrazine and 4,4'-bipyridine as bridging ligands are reported. The Co(II) complexes show only weak bonds in the chain. Stronger bonds, which are essential for the conductivity, are abserved for the Fe(II) complexes. Their conductivity is in the range of 10−9 (Ω cm)−1-. In addition, polymeric complexes have been synthesized, which consist of only metal atoms and bridging ligands. Examples are the bis-pyrazolate iron(II) and the cationic complex gold(I) 4,4'-bipyridine. Moreover the crystal structure and conductivity of two modifications of monomeric oxo-phthalocyaninato titan(IV) has been investigated.Keywords
