Homoleptic dirhodium tetraoctanoate and its pyridine adduct: synthesis and crystal structures

Transition Metal Chemistry (impact factor: 1.02). 04/2012; 35(5):585-590. DOI:10.1007/s11243-010-9367-9 pp.585-590

ABSTRACT Dirhodium tetraoctanoate (1), without any exogenous axial ligands, has been obtained in crystalline form by slow evaporation from ethanol. The molecules
are linked by axially ligating each other to form infinite chains, which is similar to the only other two structurally characterized
rhodium(II) carboxylates, Rh2(O2CCF3)4 and Rh2(O2CC3H7)4, which also lack exogenous axial ligands. The infinite chains of 1 are cleaved by strong donor solvents such as pyridine to produce the corresponding pyridine adduct (2). Both the complexes were characterized by elemental analysis, MS, IR and NMR spectra.
