Novel inorganic polymeric compounds based on the Re_4 chalcocyanide cluster complexes: synthesis and structures of Mn_2Re_4Se_4(CN)_12·6H_2O, Cd_2Re_4Te_4(CN)_12·6H_2O, Cu_2Re_4Te_4(CN)_12·4H_2O and K_4Re_4Se_4(CN)_12·6H_2O

摘要

Three new tetrahedral rhenium chalcocyanide cluster compounds, Mn_2Re_4Se_4(CN)_12·6H_2O (1), Cd_2Re_4Te_4(CN)_12·6H_2O (2) and Cu_2Re_4Te_4(CN)_12·4H_2O (3), exhibiting polymeric structures have been synthesized by the treatment of molecular ionic cluster compounds K_4Re_4Q_4(CN)_12 (Q = Se, Te) with aqueuos solutions of Mn(NO_3)_2, CdSO_4 and CuCl_2 in gel. The previously unknown starting compound K_4Re_4Se_4(CN)_12·6H_2O (4) was obtained by the reaction of Re_4Se_4(TeCl_2)_4Cl_8 with KCN in water. All four compounds have been characterized by single-crystal X-ray diffraction.
