Joining the crown family; the tetrameric, O-bridged macrocycle [{P(micro-N(t)Bu)}2(micro-O)]4.
The in situ reaction of the dianion [O_P(micro-N(t)Bu)]2(2-) with the dimer [ClP(micro-N(t)Bu)]2 gives the O_bridged macrocycle [{P(micro-N(t)Bu)}2(micro-O)]4 (1), being the largest crown-like phosph(III)azane of its type to be reported and having a structure that is directly related to the ubiquitous 12-crown-4.
