Towards high T-c octacyanometalate-based networks

We present an overview of very recent advances in the engineering of magnetic networks based on octacyanometalates. The selected magnetic networks of (CuWV)-W-II, (NiWV)-W-II and (MnLNbIV)-L-II (L - organic bridging linker) illustrate the possible strategies for tuning of the magnetic characteristics. The combination of magnetic ordering for 2D (two-dimensional) and 3D (three-dimensional) networks together with the solvent sensitivity of a cyano-bridged framework resulted in the development of a novel 3D {[Mn-II(imH)](2)[Nb-IV(CN)(8)]} assembly with magnetic sponge character, characterized by T-c of 62 K, the highest ever observed for octacyanometalate-based networks.
