Tris(ethylxanthato-κ2 S,S′)(1,10-phen-anthroline) bis-muth(III)

The title compound, [Bi(C3H5OS2)3(C12H8N2)] [systematic name: tris-(ethoxy-methane-dithio-ato-κ2 S,S′)(1,10-phenan- thro-line)bis-muth(III)], is monomeric, with the Bi atom chelated by the S atoms of three ethylxanthate ligands and the N atoms of 1,10-phenanthroline. The central BiIII atom is eight-coordinate and adopts a distorted capped-penta-gonal-bipyramidal geometry. In the crystal structure, weak C - H⋯S inter-actions and a close S⋯S contact stabilize the structure [S⋯S = 3.509 (3) Å]. © 2007 International Union of Crystallography. All rights reserved.
