cis-Bis(dimethyl sulfoxide-S)dinitratopalladium(II) and cis-dinitratobis(1,4-oxathiane-S)palladium(II)

M. H. Johansson and Å. Oskarsson

Abstract: The Pd atom in each of the two title compounds, [Pd(NO₃)₂(C₂H₆OS)₂], (I), and [Pd(NO₃)₂(C₄H₈OS)₂], (II), coordinates two O atoms from two nitrate ligands and two S atoms from dimethyl sulfoxide (dmso) and thioxane (systematic name: 1,4-oxathiane) ligands in a pseudo-square-planar cis-geometry. In the dmso complex, the distances to palladium are Pd-O 2.067 (2) and 2.072 (2) Å, and Pd-S 2.2307 (11) and 2.2530 (8) Å. The corresponding distances in the thioxane complex are Pd-O 2.053 (3) and 2.076 (2) Å, and Pd-S 2.2595 (9) and 2.2627 (11) Å. Both compounds may be regarded as dimers with an inversion centre, where one of the coordinating nitrate O atoms in one molecule also interacts with the Pd atom in the adjacent molecule, with Pd-O distances of 2.849 (9) and 3.31 (3) Å in (I) and (II), respectively.

Formula: [Pd(NO₃)₂(C₂H₆OS)₂] and [Pd(NO₃)₂(C₄H₈OS)₂]
