Abstract

Two Preyssler P5W30-based compounds: [Mn(H2O)2(DAPSC)]2{[Na3(H2O)2Mn0.5(H2O)4][Mn(H2O)(DAPSC)]2[H3P5W30O110]}·7.5H2O (1) and [Co(H2O)2(DAPSC)]{[Co(H2O)2(DAPSC)][Na1.5(H2O)2]}{[Na0.5(H2O)2Co0.5(H2O)4][Co(H2O)(DAPSC)]2[H4P5W30O110]}·6H2O (2) modified by Schiff base 2,6-diacetylpyridine bis(semicarbazone) (DAPSC) and transition metal (TM) ions have been successfully isolated and structurally characterized by IR spectroscopy, PXRD, and single-crystal XRD. Structural analysis reveals that compound 1 is composed of a {[Na3(H2O)2Mn0.5(H2O)4][Mn(H2O)(DAPSC)]2[H3P5W30O110]}4− architecture (Section A), two isolated [Mn(H2O)2(DAPSC)]2+ groups (Section B), and seven and a half lattice water molecules. Compounds 1–2 represent the first Preyssler-type compounds modified by Schiff base and TM ions. Additionally, the electrocatalytic and the third-order NLO properties have been investigated.
