Tr. Mohs et al., AN ORGANOIMIDO DERIVATIVE OF THE HEXATUNGSTATE CLUSTER - PREPARATION AND STRUCTURE OF [W6O18(NAR)](2-) (AR=2,6-(I-PR)(2)C6H3), Inorganic chemistry, 34(1), 1995, pp. 9-10
A functionalized hexatungstate cluster bearing an organoimido ligand [
W6O18(NAr)](2-), 1 (Ar=2,6-(i-Pr)(2)C6H3), is produced in the reaction
of ArNCO with [Bu(4)N](2)[WO4]. 1 is a hydrolytically stable yellow m
aterial (lambda(max)=292 nm) that can be reduced to the corresponding
trianion. Comparisons are drawn between 1, its Mo analogue, and its [W
6O19](2-) relative.
