摘要: Abstract In this paper we present the synthesis and characterisation of novel bisnickelacyclic complexes. We carried out reaction between 2,2′,2″,5′-tetralithio-1,1′,4′,1″-terphenyl nickelocene in which bisnickelacyclic–dilithium complex was formed. It represented contact ion pair that consisted nickelacyclic dianion (the first it's kind) lithium cations. Exchange solvent from diethyl ether to DME (1,2-dimethoxyethane) afforded separated ionic pair. Both these complexes exhibited paramagnetic behaviour, so structural investigations had be by means X-ray diffraction. DFT calculations were employed for better understanding electronic structure
