Abstract

Treatment of [RhCl3(Me-3[9]aneN(3))] (1) (Me[9]aneN(3) = 1,4,7-trimethyl-1,4,7-triazacyclononane) with Ag(CF3SO3) in a 1:3 ratio at 60 degrees C for 30 min in CH3CN leads to formation of the tetranuclear complex [{RhCl3(Me-3[9]aneN(3))}(2)Ag-2(CF3 SO3)(CH3CN)](CF3SO3). CH3CN (2) with a novel Rh2Ag2Cl6 core. More forcing conditions (reflux, 18 h) afford the likewise tetranuclear complex [{RhCl2(CH3CN)(Me-3[9]aneN(3))}(3)Ag](CF3 SO3)(4) (3) with an alternative Rh3AgCl6 central unit. Whereas only one Cl- ligand can also be substituted under similar conditions in DMSO to provide trinuclear [{RhCl2(DMSO-kappa O)(Me-3[9]aneN(3))} Ag-2(CH3OH)](CF3SO3)(3) (4), performing the reaction in the more polar solvent DMF allows two chlorides to be removedthereby yielding mononuclear [RhCl(DMF)(2)(Me-3[9]aneN(3))](CF3SO3)(2) (5). The coordinated DMF ligands are transformed to CH3NHCHO in [RhCl(CH3NHCHO)(2)(Me-3[9]aneN(3))](CF3SO3)(2) (6) on treating 5 with methylamine. [RhCl(mu-pyz)(2)(Me-3[9]aneN(3))] (7) (pyz=pyrazolate) reacts with (eta(5)-C5Me5)M(III) fragments to generate the dinuclear complexes [{Rh(Me-3[9]aneN(3))} (mu-Cl)(mu-pyz)(2){M(eta(5)-C5Me5)}](CF3SO3)(2) 8 and 9 (M = Rh, Ir). X-raystructures have been determined for 2-8. (C) 2000 Elsevier Science S.A. All rights reserved.
