A twofold interpenetrating 3D Keggin-based Ag(I) complex based on a flexible bis-pyridyl-bis-amide.

A Keggin-type polyoxometalate (POM)-based complex, [Ag5(L)3(H2O)2]·6H2O (1) (L = N,N′-bis(3-pyridinecarboxamide)-1,2-ethane), has been hydrothermally synthesized. Compound1shows a 3D + 3D interpenetrating network with a (3,4,4,4)-connected (4 × 62)2(42 × 62 × 82)(65 × 8)2topology, and it represents the first example of interpenetrating POM-based complex based on flexible bis-pyridyl-bis-amide ligands. Moreover, the electrochemical behavior and luminescence of1have been investigated. [ABSTRACT FROM AUTHOR]
