Two novel mono- and bi-functionalized organoimido derivatives of hexamolybdates bearing the strong electron-withdrawing nitro group, (Bu4N)2[Mo6O17(NAr)2] (1) and (Bu4N)2[Mo6O18(NAr)] (2) (Aro-NO2–C6H4) have been synthesized for the first time via the reaction of hexamolybdate ions and 2 equivalent of aromatic amines with an excessive dehydrating agent N,N′-dicyclohexylcarbodiimide (DCC). By controlling the amount of DCC, such two derivatives can be selectively prepared in reasonable yields, which have been characterized with UV/vis, IR, 1H NMR, ESI-mass spectrometry and single-crystal X-ray diffraction techniques. The influences of [NAr] ligands and [NAr] incorporation number on properties and supermolecular assembly of such two derivatives have been systematically investigated.
Mono- and bi-functionalized organoimido hexamolybdates bearing the nitro group were selectively synthesized. The [NAr] incorporation number has great influence on the properties and supermolecular structures of the compounds.Figure optionsDownload as PowerPoint slideHighlights
► (Bu4N)2[Mo6O18(NAr)] and (Bu4N)2[Mo6O17(NAr)2](Aro-NO2–C6H4) have been synthesized.
► Mono- and bi-functionalized derivatives are selectively prepared via the same route.
► The [NAr] number has great influence on supermolecular structures and properties.
► The [NAr] ligand also affects supermolecular structures and properties.
