Positive at last : The first condensed‐phase homopolyatomic phosphorus cation [P 9 ] + was prepared using a combination of the oxidant [NO] + and weakly coordinating anion, [Al{OC(CF 3 ) 3 } 4 ] − . [P 9 ] + consists of two P 5 cages linked by a phosphonium atom to give a D 2 d ‐symmetric Zintl cluster. NMR (see picture), Raman, and IR spectroscopy, mass spectrometry, and quantum‐chemical calculations confirmed the structure.
