摘要

The reaction of trivacant Keegin germanotungstate [A-α-GeW ₉O₃₄]^10- with Mn²⁺ and Ce ⁴⁺ cations in the presence of oxalate ligand under hydrothermal conditions led to the isolation of a novel organic-inorganic hybrid 3d-4f heterometallic germanotungstate K₄Na₄[Ce ₂(ox)₃(H₂O)₂]₂{[Mn(H ₂O)₃]₂[Mn₄(GeW₉O ₃₄)₂(H₂O)₂]·14H₂O (1) (ox = oxalate), which has been characterized by elemental analysis, IR spectroscopy, thermogravimetric (TG) analysis, and single-crystal X-ray crystallography. Interestingly, each tetra-Mn^II-substituted sandwich-type unit acts as 14-dentate ligands to link eight Ce³⁺ centers and six Mn²⁺ centers further into a three-dimensional (3D) architecture. The 3D structure can be considered as two parts: one is the two-dimensional layer formed by sandwich-type [Mn₄(H ₂O)₂(GeW₉O₃₄)₂] ^12- fragments and Mn²⁺ linkers; the other layer is constructed from Ce³⁺ cations and oxalate bridges, and the two layers are combined together alternately through W-O-Ce-O-W linkers, resulting in the 3D framework. Notably, 1 exhibits the first 3d-4f 3D organic-inorganic hybrid framework constructed by sandwich-type TM-substituted polyoxoanions and mixed 3d and 4f metal linkers in POM chemistry.
