[VO(TPP)] experimental spin-phonon relaxation time T1 (black circles)27 compared with other VO-based systems: VOPc (Pc = phthalocyanine, red squares)53, [(Ph)4P]2[VO(dmit)2] (dmit = 1,3-dithiole-2-thione-4,5-dithiolate, blue triangles)54 and its analogue compound with a deuterated cation, [(d20-Ph)4P]2[VO(dmit)2] (green diamonds)54. All the samples were crystalline dispersions in their isostructural diamagnetic host: [TiO(TPP)] (2% dilution), TiOPc (0.1% dilution), [(Ph)4P]2[MoO(dmit)2] (5% dilution) and [(d20-Ph)4P]2[MoO(dmit)2] (5% dilution) (error bars are within the size of the symbols).
