چکیده
In the title compound, [Au(2)Ba(NCS)(4)(C(20)H(24)O(6))](n), the dithio--cyanato-aurate(I) anion adopts a dimeric structure with an Au⋯Au distance of 3.1109 (10) Å; both Au(I) atoms are also bonded to two S atoms. The Ba(II) ion adopts an irregular BaN(3)O(6) geometry, arising from the crown ether and three adjacent thio-cyanate N atoms; the extended structure of the complex can be described as a one-dimensional coordination polymer generated by the Ba⋯N inter-actions (two on the endo side and one on the exo side of the crown ether) running parallel to the b axis, with an anti-parallel arrangement of ribbons in the unit cell.
