Description
An octacyanidometalate-based nanochannel magnet, Co7[W(CN)8]4Cl2·29H2O, is reported. Single-crystal synchrotron X-ray diffraction measurements reveal that this compound has a three-dimensional cyanido-bridged network based on {Co5W4}n columns situated along the c-axis. The channels resemble a lotus root and have a remarkably large diameter of 1.4 nm, which corresponds to a 44% vacancy. Although the channel size is very large, the compound exhibits ferromagnetic ordering with a Curie temperature of 29 K and coercive field of 5500 Oe. Such a ferromagnetic lotus root can adsorb large molecules and may realize host–guest chemistry in ferromagnets.
