The preparations and structures are described of four new polyoxostibonates, [Co(p-MeC6H4Sb)12O28Co(H2O)3}4]Cl2·6H2O, [Co(p-ClC6H4Sb)12O28Co(H2O)3}4]Cl2·22H2O, (PhCH2NMe3)2[Zn(p-ClC6H4Sb)12O28Zn4Cl2.54Br1.46]·8MeCN·H2O and [BaCoH4(p-MeC6H4Sb)O28]·5H2O. Each of these has a framework of 12 (RSb) groups linked by 28 O atoms, with one transition metal ion in a tetrahedral site in the centre. Other metal
