    <dcterms:abstract xml:lang="eng">We report the synthesis and X-ray structures of four Rh 2 (O 2 Ac) 4 (L Ax ) 2 (OAc = acteate, CH 3 COO - ) paddle-wheel complexes ( C1 - C4 ) with methylthio-modified axial ligands L Ax derived from benzamidine ( L1 ), anilinopyrimidine ( L2 ) or isothiourea ( L3 , L4 ) that are capable of forming N‑H×××O hydrogen bonds to the equatorially bridging acetate ligands. This was done with the aim to suppress dissociation of the axial ligands and to make the complexes amenable to single-molecule conductance measurements in a scanning tunneling microscope break-junction (STM-BJ) setup. The characteristic spectroscopic features (NMR, IR, vis), crystal structures, the hydrogen-bonding motifs and a DFT-based screening of their frontier molecular orbitals are presented. Our calculations suggest that hydrogen-bonding stabilizes axial ligand binding by 20kJ/mol to 30 kJ/mol and that the HOMO of the rhodium paddle-wheels is closer to the Au Fermi level than the LUMO, so that the rhodium paddle-wheels are expected to constitute hole conductors.</dcterms:abstract>
