designed for a self-assembled [2 × 2] grid system. HLnitnitnitnit is not stable in methanol and slowly undergoes a disproportionation, during which the nitronyl nitroxide radical converts to the diamagnetic amidino oxide. In situ reaction of HLnitnitnitnit with Cu(BF4)2 in methanol depending on the reaction time affords self-assembled [2 × 2] grids (Lnitnitnitnit)2(L)2Cu(II)4(BF4)4·CH3OH (1) or (Lnitnitnitnit)0
