Notes:
Complexes of Third Group Elements with [(en)2MIII(OH)2] Ligands (M = Cr, Co)Heteronuclear complexes are formed on reaction of cis-[(en)2-MIII(OH)(H2O)]2+ (M = Cr, Co; en = ethylenediamine) with A1III, GaIII, InIII, and T1III in aqueous solution. The following salts with tetranuclear cations have been isolated: [A1{(OH)2-Cr(en)2}3](S2O6)3 · 13 H2O (1), [A1{(OH)2Co(en)2}3](S2O6)3 · 5 H2O (2), [Ga{(OH)2Co(en)2}3](S2O6)3 · 5 H2O (3), [In{(OH)2-Cr(en)2}3](S2O6)3 · 6 H2O (5), and [In{(OH)2Co(en)2}3]-(ClO4)4Cl2 · 4 H2O (6). Furthermore, the dinuclear neutral complexes [InCl4{(OH)2Cr(en)2}] (4) and [TlCl4{(OH)2-Cr(en)2}] · 0.5 H2O (7) are prepared. X-ray analyses confirm that in all cases the [(en)2MIII(OH)2] groups act as bidentate ligands in the hydroxo-bridged heterometallic complexes.
