Crystal analysis by Clifford George, Jacqueline Ruiz Ferrer, Paul M. Lahti,

This molecule was synthesized first by Jacqueline Ruiz, and reported in Paul M. Lahti, Jacqueline R. Ferrer, Clifford George, Patricia Oliete, Michel Julier, Fernando Palacio, Polyhedron, 20, 1465-1473 (2001). It is structurally similar to 2-(N-tert-butylaminoxyl)-benzimidazole (Jacqueline R. Ferrer, Paul M. Lahti, Clifford George, Guillermo Antorrena, Fernando Palacio, Chem. Mater., 11, 2205-2210 (1999)), also made by Jacqui; its crystal packing is also similar, being dominated by H-bonded chains connecting H-bonded stacks of radicals.

This molecule exhibits antiferromagnetic exchange coupling consistent with 2-D pseudo-planar Heisenberg behavior, as reported in the Polyhedron reference given in the previous paragraph.  Again, this is similar to the behavior of the analog 2-(N-tert-butylaminoxyl)-benzimidazole.  Overall, simlar structure led to similar crystal packing led to similar magnetic behavior, a classic structure property correlation.
