Investigatons of modified interlayer coupling in the anisotropic antiferromangnet [Cu(pyz)2(HF2)]SbF6


Investigatons of modified interlayer coupling in the anisotropic antiferromangnet [Cu(pyz)2(HF2)]SbF6

Beyer, R.; Manson, J. L.; Schlueter, J. A.; Wosnitza, J.

In recent years, many synthetic strategies have emerged with regard to the crystal engineering of functional magnetic materials. The group of J.L. Manson et al. were able to grow single crystals of a quasi-2D antiferromagnet Cu(pyz)2(HF2)]SbF6 and a defective polymorphic pendant [Cu2(pyz)4F(HF)(HF2)2 where 50% of the HF2 - links are broken, leading to two crystallographically unique Cu2+ sites. The chemical composition remains unchanged, the structural configuration indicates a minor Jahn-Teller distortion. We studied the two branches of this compound by means of magnetization and specific heat measurements, in order to get a better understanding of the importance of H-F hydrogen bonds for establishing long-range magnetic ordering in polymeric quantum magnets.
