Two {Dy2} single-molecule magnets formed via an in situ reaction by capturing CO2 from atmosphere under ambient conditions.

Under ambient conditions, CO2 was captured from atmosphere and reduced for sequestering CO2 into two {Dy2} single-molecule magnets through an in situ organic ligand reaction of hydrazine. A reasonable reaction mechanism is proposed, which provides a promising route towards the capturing and transforming CO2 into single-molecule magnets.
