Аннотация:The crystal structure of bulk microcrystalline material obtained by interaction of two rigid building blocks, namely dirhodium(II) tetra(trifluoroacetate), [Rh-2(O2CCF3)(4)], and bis(4'-pyridyl) diphenylsilane, (C6H5)(2)Si(C5H4N)(2), has been solved ab initio using X-ray powder diffraction data. The title product of the 1:1 composition, [Rh-2(O2CCF3)(4).(mu(2)-(C6H5)(2)Si(C5H4N)(2))], is a one-dimensional zigzag polymer built on axial Rh...N interactions averaged at 2.16 Angstrom. Its structural characterization complements the previously reported product of the 2:1 composition obtained from the same reaction, namely {[Rh-2(O2CCF3)(4)](2).(mu(4)-(C6H5)(2)Si(C5H4N)(2))}. The latter has a 2D layered network revealed by the single crystal diffraction study. A combination of powder and single crystal X-ray techniques is shown to be methodologically important and complementary for understanding of product assembling in the system.
