Technetium chalcogenides

Tabic 12.15.A Dimensions of the nionoclinic unit cells for the ternary technetium chalcogenides [S26. ... 

The alkali metal rhenium- and technetium chalcogenide clusters described in Section 5.6 are also octahedral.These clusters have M6Es units with eight face-capping anions on the octahedral faces in contrast to the niobium halide or oxide clusters. The A4M6S14 (A = alkali metal, M — Re, Tc), Cs6Rc6Si2, and...

There is an extensive and complex chemistry of [Re6(/A-X)D(/i,-Y)8- ] species, where X may be exclusively S or Se, or there may be a mixture of chalcogenide and halide (Y) bridges.13 There are also technetium clusters with Tc6 octahedra and allegedly only 5 face bridges, e.g., [Tc6(/u.3-Br5)Br6]1 2, but they require better characterization.
