Abstract

Polyoxoniobate [GeNb₁₈O₅₄]^14 − and polyniobotungstate [Nb₃W₃O₁₉]^5 − are firstly found to co-crystallize at the same crystal to form a rare organic–inorganic hybrid polyoxometalate H[Cu(en)₂(H₂O)]₈[Cu(en)₂(H₂O)₂]₂{K₄[Cu(en)₂]₂[Cu(en)₂(GeNb₁₈O₅₄)]₂}[Nb₃W₃O₁₉]·32H₂O (1). Interestingly, in 1, the crescent-shaped polyoxoanions [GeNb₁₈O₅₄]^14 − can form dimeric secondary building units (SBUs) {[GeNb₁₈O₅₄]₂[K₂(H₂O)₅]₂} via the linkage of K⁺ cations. These dimeric SBUs can be further bridged by copper complexes to generate 1D infinite double strand chains with completely different isolated polyoxoanions [Nb₃W₃O₁₉]^5 − filling the gaps between chains.
