he three-dimensional cyano-bridged bimetallic compound of formula [{Co(H2O)2}2Mo(CN)8]·4 H2O is described. The single-crystal X-ray structural determination revealed that the compound has a polymeric structure based on a network of [MoIV(CN)8] units and CoII ions. Each Mo(CN)8 building block is linked to Co ions through its eight CN ligands and each CoII centre is connected to four Mo units forming a highly symmetrical three-dimensional framework with square-shaped channels running through the structure. The magnetic behaviour in the temperature range 2–300 K and spectroscopic data are reported as well...
