C. Reisner et W. Tremel, TEMPLATE SYNTHESIS OF [CR(EN)(3)][TE-6] - A NOVEL POLYTELLURIDE WITH A FRAMEWORK STRUCTURE, WHOSE CAVITIES ARE FILLED WITH A [CR(EN)(3)](3+) TEMPLATE, Chemical communications, (4), 1997, pp. 387-388
[Cr(en)(3)][Te-6] (en = ethylenediamine) is obtained by a template syn
thesis under solvothermal conditions from Cr(CO)(6) and BaTe4; its cry
stal structure contains a polymeric Te-6(3-) framework whose pores con
tain the Cr(en)(3)(3+) template; [Cr(en)(3)][Te-6] is the first chalco
genide with a porous three-dimensional framework structure.
