2D Quantum Coordination Frameworks

Coordination framework materials, where metal ions are connected by molecular ligands into extended networks, are modular: their components can be exchanged while retaining the overall structural topology. This modularity allows for design strategies that are challenging to realise in conventional atomic inorganic materials. In this talk I will discuss recent work from the Cliffe Group realising quantum properties in coordination frameworks, particularly with reference to neutron scattering studies of their properties.<br/>In particular I focus on our work on 2D materials, including non-collinear magnetism in post-perovskite metal thiocyanates, single layer ferromagnetism in Ni(NCS)₂; and new routes to long-sought quantum phases such as topological <i>S</i>=2 Haldane phase.
