Porous Magnets Based on Copper–Octacyanotungsten Containing Noncoordinated Alcohol Molecules

Two types of molecule-based magnets CuII3[WV(CN)8]2(pyrimidine)2·2-propanol·6H2O (1) and CuII3[WV(CN)8]2(pyrimidine)2·1-butanol·5H2O (2) are prepared. These compounds have a 3-dimensional porous structure, in which a noncoordinated 2-propanol or 1-butanol molecule is penetrated. These compounds show long-range magnetic ordering with Curie temperatures of 8.2 K (1) and 8.4 K (2) although large organic molecules are packed.
