The novel linking of three P 3 rings by one central atom was realized in the title compound 1 , which owes its existence to the relatively large covalent radius of antimony. Condensation of the stannylated cyclotriphosphane ( t BuP) 2 PSnMe 3 with SbCl 3 (3:1) results in formation of 1 together with a configurational isomer, whose structures were elucidated by 31 P‐NMR spectroscopy. Compound 1 , a yellow solid, decomposes above −30°C and upon exposure to daylight with elimination of antimony.
