4,4′,4′′-(Methane­triyl)triphenyl tris­(2,2,5,5-tetra­methyl-1-oxyl-3-pyrroline-3-carboxyl­ate) benzene tris­olvate

In the asymmetric unit of the title compound, C(46)H(52)N(3)O(9)·3C(6)H(6), two of the benzene solvent mol­ecules are located in general positions and two are disposed about inversion centers. One of the benzene mol­ecules on an inversion center was grossly disordered and was excluded using the SQUEEZE subroutine in PLATON [Spek (2009 ▶). Acta Cryst. D65, 148–155]. In addition, one of the 2,2,5,5-tetra­methyl-1-oxyl-3-pyrrolin-3-ylcarbonyl groups is disordered over two orientations with refined occupancies of 0.506 (2) and 0.494 (2). The 1-oxyl-3-pyrroline-3-carboxyl­ate groups are essentially planar, with mean deviations from the planes of 0.026 (2), 0.012 (2), 0.034 (4) and 0.011 (4) Å. In the crystal structure, mol­ecules are connected by five weak inter­molecular C—H⋯O and four weak inter­molecular C—H⋯π(benzene) inter­actions.
