摘要

Two-dimensional cesium bimetal cyano-bridged assemblies Cs_4~ICo~(II)[Mo~V(CN)_8]Cl_3 (CsCoMo) and Cs_4~ICo~(II)[W~V(CN)_8]Cl_3 (CsCoW) were synthesized. The negatively charged and solvent-free {Co~(II)[M~V(CN)_8]Cl_3}~(4?) (M = Mo, W) coordination layers are separated by Cs~+ ions. Themogravimetric measurements show that these compounds reveal high thermal durability up to 523 K (250 °C), which is due to the absence of solvent molecules in their crystal structures. The magnetic measurements show that CsCoMo and CsCoW are metamagnets showing the field-induced transition from an antiferromagnetic phase with Ne?el temperature of 25 K to a ferromagnetic phase, which is observed at high critical magnetic field of 24 kOe at 1.8 K. These originate from antiferromagnetic interactions between ferromagnetically coupled cyano-bridged Co~(II)?M~V layers, and the contribution from single-ion anisotropy of Co~(II).
