Abstract
Through the use of a flexible ligand 1,1′-bis(3,5-dimethyl-1H-pyrazolate)methane (H2bdpm), a K-encapsulated Preyssler-based complex, [Cu4(H2bdpm)4(H2O)10(H6KP5W30O110)]·2(H2bdpm)·14H2O, has been synthesized under hydrothermal conditions. Single crystal X-ray diffraction analysis shows that the complex contains rare K-encapsulated Preyssler anions, which are linked by binuclear cyclic clusters [Cu2(H2bdpm)2]4+ to form a 1D chain. Adjacent chains are further connected by abundant intermolecular forces to construct a 2D supramolecular framework. The photocatalytic and electrochemical properties of the complex have been investigated.
Graphical abstract
(1) The Preyssler-based POM-TMCs are rarely reported. (2) The K-encapsulated Preyssler anion is uncommonly observed in Preyssler-based compound. (3) Preyssler anions are linked by binuclear CuII clusters to form a 1D chain. (4) Compound 1 exhibits photocatalytic and electrochemical properties.
