title: Variation of hydrogen-bonded networks in hexafluorophosphate salts of amidate-bridged dirhodium(II,III) complexes with axial aqua ligands.
abstract: In diaquatetra-mu-acetamidato-kappa(4)N:O;kappa(4)O:N-dirhodium(II,III) hexafluorophosphate, [Rh(2)(C(2)H(4)NO)(4)(H(2)O)(2)]PF(6), and diaquatetra-mu-acetamidato-kappa(4)N:O;kappa(4)O:N-dirhodium(II,III)hexafluorophosphate dihydrate, [Rh(2)(C(2)H(4)NO)(4)(H(2)O)(2)]PF(6).2H(2)O, the cations and anions lie on inversion centers. Diaquatetra-mu-propionamidato-kappa(4)N:O;kappa(4)O:N-dirhodium(II,III) hexafluorophosphate dihydrate, [Rh(2)(C(3)H(6)NO)(4)(H(2)O)(2)]PF(6).2H(2)O, and diaquatetra-mu-butyramidato-kappa(4)N:O;kappa(4)O:N-dirhodium(II,III) hexafluorophosphate, [Rh(2)(C(4)H(8)NO)(4)(H(2)O)(2)]PF(6), crystallize with two crystallographically independent complexes that lie on inversion centers. In all of the structures, the dirhodium units are hydrogen bonded to one another. The hydrogen-bonded networks vary with the alkyl substituents.
