Description
Summary:Two new compounds, Cs 2 [Cu 2 Re 6 S 8 (CN) 6 ]⋅3H 2 O ( I ) and (H 3 O) 2 [Cu{Cu 2 (µ-CN)}Re 6 Se 8 (CN) 6 ]·6.5H 2 O ( II ), were synthesized under hydrothermal conditions from a mixture of CuCN and Cs 2.67 K 1.33 [Re 6 S 8 (CN) 2 (OH) 4 ]·4H 2 O or Cs 2.75 K 1.25 [Re 6 Se 8 (CN) 4 (OH) 2 ]·H 2 O, respectively. The reaction involves replacement of OH – by CN – and the formation of interpenetrating anionic framework through –CN–Cu–CN– bridges. The framework cavities accommodate counterions and water molecules. The obtained compounds were characterized by single crystal X-ray diffraction (CIF files CSD nos. 2048821 ( I ), 2048822 ( II )), IR spectroscopy, and elemental analysis.
