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)2 4 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 (N-HaO=C) 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 (N-HaO-Mo) 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.

New lipophilic diamide compounds have been synthesized and tested as ionophores for lithium in poly(vinyl chloride) (PVC) membrane electrodes, including compounds with pyridine, furan, dioxanonane, and polyether backbones with different lipophilic diamide groups. The new ionophores were compared with previously reported ionophores under similar measurement conditions with the same plasticizer, tris(2-ethylhexyl) phosphate, in all membranes. Fixed interference and matched potential methods were used to determine relative selectivity coefficients for all the electrodes.
