Synthesis and X-ray crystallographic characterization of two different inorganic–organic hybrid isopolyoxomolybdates with α-dipropylammonium N,N-diisobutylacetamide by varying reaction conditions
چکیده انگلیسی

Two new polyoxomolybdate based inorganic–organic hybrid compounds have been obtained from same ammonium ion ligand 1 and molybdate source just by altering reaction conditions. The new hybrid polyoxomolybdate complexes (LH)2[Mo6O19] 3 and (LH)4[Mo8O26] (MeCN)24 have distinct structural features revealed by X-ray crystallographic studies. The complex 3 contains two ammonium ligands to balance the charge on hexamolybdate dianion. The most striking feature of (LH)2[Mo6O19] is the presence of inter-ligand hydrogen bonding (NH⋯OC) between two ligands arranged in an antiparallel fashion that favors the formation of a net like structure which embeds the Mo6O19 dianion. The complex 4 contains four ammonium ligands to balance the charge on β-octamolybdate tetraanion. Interestingly, complex 4 exhibits strong hydrogen-bonding interactions between ammonium ligand and octamolybdate anion (NH⋯OMo) and no inter-ligand H-bonding interaction. The different structural features of hybrid compounds 3 and 4 suggest that different polyoxomolybdate clusters play a key role in the process of assembling of ligands.
