[{C 8 H 12 Rh} 33 ‐OH) 2 ]SbF 6 : Ein neuer metallorganischer Rhodiumkomplex mit Rh 3 O 2 ‐Kern

Abstract: Crystals of C 24 H 38 F 7 O 2 Rh 3 Sb (3) obtained from the crystallisation of 2 from wet solvents consist of [{C 8 H 12 Rh} 3 (l 3 -OH) 2 ] + cations connected with the SbF 6 ± anions via hydrogen bonds. In the cations, the Rh 3 faces are bicapped by OH ± ligands.

“…This “formally ionic” species crystallizes as neutral chains originating from the presence of strong OH···F−H−F···HO (the O···F distance is near 2.50 Å) hydrogen bonds between the trinuclear complex cation (Figure ) and the bifluoride anion. The very same cation has been previously observed in the SbF 6 - salt . Interestingly, besides having a similar molecular stereochemistry, the two species also share some analogies at the supramolecular level.…”

“…Although the first one is rather short (with the caveats inherent in the XRPD method), this effect should not be surprising because the few known structures containing the Rh 3 (µ 3 -OX) 2 core show a large variability in the Rh-Rh contacts (2.87-3.12), which are then to be considered rather flexible. 20,21 In particular, the closely related SbF 6salt, cited above, shows an isosceles triangle metal core with similar distances.…”

“…X-ray analysis of a yellow crystal thus grown directly from the reaction solution revealed the structure of 1 to be [(COD) 3 Rh 3 (μ 3 -OH) 2 ] + HF 2 - (Figures and ), a cationic trinuclear hydroxo complex with bifluoride as the counterion. The cationic core [(COD) 3 Rh 3 (μ 3 -OH) 2 ] + has been previously reported once, in the form of the SbF 6 - salt. Because the geometry parameters found for the cation of 1 are almost identical with those reported for [(COD) 3 Rh 3 (μ 3 -OH) 2 ] + SbF 6 - , the structure of 1 will not be discussed in detail herein.…”
