Colourless single crystals of the title compound are obtained from a saturated solution of NaOSiPh3 in toluene in a humid atmosphere. We have characterized [Na4(OSiPh3)H2O)3] by IR spectroscopy and by a crystal structure determination. Space group R3, Z = 6 , R = 0.056. Lattice dimensions at -70°C: a = b = 1540.3 pm, c = 2639.6 pm. The compound has the structure of a Na4O4 heterocubane which is only slighty distorted and in which one of the sodium atoms is not hydrated and shows coordination
