Phenyltelluroxane clusters of the composition [{(PhTe) 19 O 24 } 2 I 18 (solv)] (1)a re formed during the hydrolysis of [PhTeI 3 ] 2 or the oxidation of various phenyltellurium(II) compounds with iodine under hydrolytic conditions.T he compounds consist of two half-spheres with a{(PhTe) 19 O 24 } 9+ network, which are connected by 18 iodine atoms.T he spherical clusters can accommodate solvent molecules such as pyridine or methanol in the center of two rings formed by iodine atoms.T he presence

Acrownether-like coordination by six oxygen atoms of the telluroxane network is found for the {Ca(H 2 O} 2 } 2+ and {Y-(NO 3 )(H 2 O)} 2+ building blocks.M ass spectrometric studies show that considerable amounts of the intact clusters are transferred to the gas phase without dissociation.
