A family of heterometallic [Cat][Tix MO(x+1 )(O2 Ct Bu)2x+2 ] rings is reported where Cat=a secondary or tertiary alkyl ammonium ion, x=7, 8 or 9, and M=FeIII , GaIII , CrIII , InIII and AlIII . The structures are regular polygons with eight, nine or ten vertices with each edge bridged by an oxide and two pivalates. The size of the ring formed is controlled by the alkylammonium cation present. In each case a homometallic by-product is found [Cat][Tix O(x+1 )(O2 Ct Bu)2x-1 ].
