Abstract:
Constructing multiple functional geometric frustration magnets is a hot topic in solid state chemistry and material science. Herein, a two‐dimensional (2D) parallel interpenetrating “star” net complex [HDMPDA][Fe 6 ( μ 3 ‐O) 2 ( μ ‐O 2 CH) 15 ] ( 1 ) was obtained successfully with HDMPDA (DMPDA=N, N’‐dimethyl‐1,3‐propanediamine) as charge balancer. The dipole reorientation of the rotator [HDMPDA] + in the complex brings a structure transition which leads dielectric relaxation close to room temperature. Despite strong antiferromagnetic coupling existing between ions in the net, long‐range order temperature T N of the complex is suppressed to 4.2 K by geometric frustration. Interestingly, below T N , a canted antiferromagnetic state, accompanied with slow magnetic relaxation, is detected due to the lack of enough magnetic coupling between 2D layers. Thus, 1 is a particular multifunctional magnetic frustration material containing two different types of relaxations.
