title: Two phosphaalkene radical cations with inverse spin density distributions.
abstract: Two phosphaalkene radical cations 1(•+) and 2(•+) have been reported. 1(•+) is stable in the solid state and has been structurally characterized. 2(•+) only remains persistent in solution. 1(•+) is described as a phosphorus-centered radical, while 2(•+) as a delocalized radical with little contribution from phosphorus.
