Following a tripod‐coupling strategy a new phosphane oxide cage compound was synthesised in comparatively high yield. The X‐ray crystal structure obtained shows a large cavity and an out ‐positioned P=O moiety in the solid state. A stable in ‐isomer was not detected, either during synthesis or by isomerisation. We attribute this fact to homeomorphic isomerisation in solution at room temperature.(© Wiley‐VCH Verlag GmbH & Co. KGaA, 69451 Weinheim, Germany, 2008)
