Acta Crystallographica Section E Structure Reports Online (Impact Factor: 0.35). 12/2009; DOI: 10.1107/S1600536809045218/hb5102sup0.html
In the title compound, [Au2Ba(NCS)4(C20H24O6)]n, the dithiocyanatoaurate(I) anion adopts a dimeric structure with an Au...Au distance of 3.1109 (10) Å; both AuI atoms are also bonded to two S atoms. The BaII ion adopts an irregular BaN3O6 geometry, arising from the crown ether and three adjacent thiocyanate N atoms; the extended structure of the complex can be described as a one-dimensional coordination polymer generated by the Ba...N interactions (two on the endo side and one on the exo side of the crown ether) running parallel to the b axis, with an antiparallel arrangement of ribbons in the unit cell.
