The exposure of CrCl2(THF)2 to 1 equiv. of TEMPO and 1 equiv. [TEMPO]Na afforded (η2-O,N-TEMPO)2CrCl (1, 67%); addition of [TEMPO]Na to 1 yielded (η2-O,N-TEMPO)2Cr(TEMPO) (2). Both 1 and 2 exhibit pseudo-pentagonal planar (PPP) geometry, instead of myriad alternatives. Calculations and spectral studies suggest the solid-state geometry persists in solution.
