Abstract
We synthesize and characterize the magnetic and thermodynamic properties of the quasi one-dimensional organic-inorganic hybrid ANiCl3compounds [A = N(CH3)4+, CH3NH3+, (CH3)2NH2+, C(NH2)3+, and CH(NH2)2+]. Additionally, the crystal structure of (CH3)2NH2NiCl3is reported. These materials possess chains of face-sharing NiCl6octahedra in a triangular array. The chains run in one direction and are separated from one another by organic cations of different sizes and geometries. In accordance with the 90° superexchange model, we find that the nature of the magnetic coupling within chains can be predicted by the value of the Ni-Cl-Ni angle. As the Ni-Cl-Ni angle decreases from 90°, the magnetic interactions become increasingly antiferromagnetic. These findings provide a foundation for predicting the magnetic properties of quasi one-dimensional organic-inorganic hybrid ANiCl3compounds.
