Co-ordination complexes of polyoxomolybdates with a hexanuclear core: synthesis and structural characterization of (NBun 4)2[Mo6O18(NNMePh)]

Abstract

Reaction of [MoCI4(NNMePh)] with ( B u ~~N ) ~[ M o ~O ~] yields a co-ordination complex with the hexanuclear oxomolybdate core, ( B u ~~N ) ~[ M o & ~( NNMePh)]; the reaction is general with appropriate precursors in providing a ready entry into the class of co-ordination compounds of the types [Mo5018(ML)]* and [W5018(ML)]*, with M = Mo or W and L = NNR2, NR, or N.

Aliphatic Organoimido Derivatives of Polyoxometalates Containing a Bioactive Ligand

“…[43][44][45] For example, imidoylization of POMs was first discovered by Zubieta and Kang, [20] and then largely investigated and developed by Maatta et al, [21,[24][25][26] Proust et al, [22] and Errington et al [23] by introducing three basic approaches including reactions with phosphinimines, isocyanates, and aromatic amines.

Synthesis and Properties of Oxygen‐Centered Tetradecaimido Hexatantalum Clusters

“…The discovery of these new compounds occurred serendipitously during our investigation of the hydroamination of alkynes by anilines with the imido catalyst [Bn 3 Ta=NtBu] (1). [7] Reaction mixtures often developed a red color during the course of the reaction, and catalyst deactivation was always observed within 24 hours regardless of the amount of 1 added (Scheme 1).…”

“…[1] The terminal oxo ligands in hexamolybdate and hexatungstate have been replaced to varying degrees by imido [2] or hydrazido [3] groups, and cyclopentadienyl-functionalized hetero-hexanuclear clusters have been prepared. [4] Still, incorporation of organic groups into the bridging sites has been more challenging.…”

“…L] nÀ in which L is a nitrogenous ligand. Following the pioneering investigations by Zubieta and co-workers, [46] this family of polyanions has been extended by Errington, Maatta, Proust, Peng and Wei groups [32] and now includes nitrosyl, [47][48][49] hydrazido, [50] diazenido [46,[51][52] nitrido [50] and imido [53][54][55][56][57][58] derivatives. One diazoalkane derivative has been also reported by Maatta and coworkers.…”
