Abstract
The reaction of (Bu4N)2[Mo6O19] with 8-aminoquinoline in the presence of DCC (N,N′-dicyclohexylcarbodiimide) afforded the cis-dioxo-Mo(VI) amide [MoO2(NHC9H6N)2], which was characterized by spectroscopy, mass spectrometry, 1H NMR, and single-crystal X-ray analysis. X-ray crystallography shows that the complex exhibits a distorted octahedral geometry with each oxo ligand trans to the quinolyl nitrogen and the amido ligands are bound to the metal in an N,N-chelating fashion. The molecules form zigzag chains via C–H ··· O hydrogen bonds and the chains are connected into networks through interchain N–H ··· O hydrogen bonds.
