A new class of easily generated TCNQ2--based coordination polymers

Abstract

New types of coordination polymers containing [M(TCNQ)] sheets in which the TCNQ component is present as the little known dianion TCNQ2- are obtained in a very simple manner using readily available TCNQH2 (i.e. 1,4- (NC)2CH·C6H4 3·CH(CN) 2) as the starting material. Above and below the metal centers in the sheets, a range of pyridine derivatives can be attached, some terminal and some acting as pillars linking sheet to sheet to form a 3Dcoordination network. The following compounds, generally in solvated form, were isolated and structurally characterized;[M(TCNQ)(pyridine)2] (M=Mn or Zn), [M(TCNQ)(quinoline) 2] (M=Co or Zn), [Mn(TCNQ)(4-methylpyridine)2], [Zn(TCNQ)(4-phenylpyridine)2], [Zn(T..
