Article abstract of DOI:10.1039/DT9950001645

A series of manganese(II) complexes <> (E = Se, R' = Me or t-Bu; E = Te, R' = Me) have been prepared by photolysis of 2(thf)> (thf = tetrahydrofuran) with the corresponding sterically demanding arenechalcogenols 2,4,6-R'3C6H2EH.Complexes with R' = Me form co-ordination polymers which are soluble only in strongly co-ordinating solvents, while complexes with R' = t-Bu are dimeric and readily dissolve in less polar solvents such as toluene.The complexes react with Lewis bases (PMe3, 2,2'-bipyridyl) to form tetrahedral or octahedral adducts, depending on the steric requirements of the arenechalcogenolate ligands.The structure of <_infinite> was determined by X-ray diffraction.The compound forms a one-dimensional infinite chain with bridging selenolate ligands which surround the metal centre in a flattened tetrahedral geometry.
