Description
Summary:Iron complexes derived from 6-diaminotriazyl-2,2-bipyridines display spin crossover behaviour, and hydrogen bonding-controlled self-assembly with a suitable barbiturate partner can modulate the crossover from mixed low and high spin to high spin. This system is the first to use solution-phase self-assembly of complementary hydrogen-bonding organic species to modulate spin state. Hydrogen bonded self-assembly of 6-diaminotriazyl-2,2-bipyridine-Fe( II ) complexes with barbiturate allows control of spin state and modulates the crossover from mixed spin to high spin. This system is the first to use solution-phase hydrogen-bonding self-assembly to modulate spin state at metal centres.
