An attempt to prepare trinuclear tungsten oxoalkoxides [BzMe3N]3[W3O8(OMe)5] from the reaction between
WO2(OMe)2, [BzMe3N]2WO4 and [BzMe3N](OMe) in the ratio of 2:1:1 in MeOH produced
[BzMe3N]2[Na2W4O12(OMe)4(MeOH)6].6MeOH. Suitable crystals for X-ray chrystallographic studies were obtained
from hot mixture of methanol-acetonitrile solution. The I.R., 1H-NMR, and microanalysis data including crystal
structure of [Na2W4O12(OMe)4(MeOH)6]2- anion are reported...

In an attempt to synthesize [BzMe3N]2Mo2O5(OMe)5 from the reaction of [BzMe3N]2MoO4 and MoO(OMe)4 in the
ratio of 1:1 in methanol has produced [BzMe3N]2Mo4O10(OMe)6. The formation of [Mo4O10(OMe)6]2- anion
suggests that ligand dissociation has occured in solution. Suitable crystals for X-ray chrystallographic were obtained
from hot methanol and the crystal structure of [BzMe3N]2Mo4O10(OMe)6 has...
