Trigonal prismatic co-ordination of sodium by oxygen: the crystal structure of tris[bis(diphenylphosphinyl)methane]sodium bromide hydrate
Abstract
In the crystal of the complex [{Ph2P(O)·CH2·P(O)Ph2}3Na]Br,3H2O the cation consists of three molecules of the bis(phosphine oxide) chelating a sodium ion by a trigonal prismatic arrangement of six oxygens.
